              positions.  Always broken (svgtopam was new in Netpbm 10.33
              (March 2006)).

              libnetpbm: fix bug: pm_system_XXX closes Standard Input if you
              supply a Standard Output accepter but not a Standard Input
              feeder.  Broken since Netpbm 10.40 (September 2007).

              Windows: fix bug: pm_system_lp() and pm_system_vp() fail
              silently instead of with a clear error message in an environment
              that does not provide Unix process management.  Always broken.
              (pm_system_lp and pm_system_vp were new in Netpbm 10.40
              (September 2007), but wouldn't even compile until Netpbm 10.42
              (March 2008)).

              installnetpbm: Accept globs for directory name responses
              (notably, ~/DIR).

              Build: don't try to build standardppmdfont.c if it already
              exists (so don't require ppmdcfont to exist).  Broken around
              Netpbm 10.35 (2006).

              Build: Define _XOPEN_SOURCE=500 in source files that use M_PI.
              While C libraries in the past have always provided this with
              just _XOPEN_SOURCE=null, it appears that M_PI is actually
              defined by Single Unix Specification 2, aka UNIX98, for which
              you need _XOPEN_SOURCE=500, and Cygwin has changed to enforce
              this.

              Build: document MinGW _XOPEN_SOURCE incompatibility and add
              warning to Configure.

              Debian packaging: fix bug: don't try to include Manweb files, as
              it is no longer packaged by 'make package'.

17.03.28 BJH  Release 10.78.00

              ppmpat: Add -color.

              ppmpat: Add -argyle1, -argyle2.

              pnmtotiff: Fail with -miniswhite or -minisblack on color image
              rather than produce an invalid TIFF.

              tifftopnmcmyk: Default rows per strip to the TIFF library
              default instead of whatever yields 8K strips.

              --version global option: with SOURCE_DATE_EPOCH environment
              variable, display source code datetime instead of build
              datetime.  And when displaying build datetime, do it in the
              local time of the process running the command instead of the
              process that did the build.

              tifftonm: Fix incorrect PBM output with two-color paletted TIFF
              image.  Broken in primordial Netpbm, ca 1990.

              tifftopnm: Fix memory corruption when image is more pixels than
              can be represented as a C unsigned integer.  Broken in Netpbm
              10.11 (October 2002).

              tifftopnmcmyk: Fix bug: fails with very wide images and no
              -rowsperstrip.  Always broken.  (Tifftopnmcmyk was new in Netpbm
              8.2 (March 2000).

              (ppmd_fill_path was new in Netpbm 10.34 (June 2006).

              Build: don't create pointer man pages anymore.  These were
              classic man pages, created by 'make package', one for each
              program, that just told the user to get the manual from the web
              and that other options for manuals are available at install
              time.  Getting documentation online is commonplace enough now
              that the user doesn't need to be told to do it or that there are
              other options.  The existence of pointer man pages was,
              meanwhile, misleading, since it looked from the outside like
              they actually contained documentation.

              Build: Don't package or install Manweb setup (for accessing
              manuals on the web with Manweb).  Probably 100% unused and
              distracting.

              Debian package: change dependencies to be compatible with
              Debian 8.

              present.  (New in Netpbm 1 (March 1991)).

              pbmtopi3: Fix bug: wrong output when input is higher or wider
              than 640 pixels.  Always broken (pbmtopi3 was new in September
              1991).

              st4topgm: Fix bug: with no argument, uses file named "'" instead
              of Standard Input.  Always present (st45topgm was new in Netpbm
              10.70 (March 2015).

              pbmtomgr: Fix incorrect output when input is too large (must be
              at most 4095 pixels high or wide).  Always broken.  (pbmtomgr
              was new in 1989).

              pbmtomacp: fix wild pointer dereference with -b larger than
              image height.  Always broken.  (pbmtomacp was new in X.V11R3
              (March 1988).

              ppmtorgb3: Fix buffer overflow with long input file name.
              Always present.  (ppmtorgb3 was new in X.V11R4 (November 1989).

              ppmtoarbtxt: fix bug: wrong output when high numbers represent

              ppmtoarbtxt: better rounding in sample values.

              libnetpbm: Remove bitio.h as an external interface.

              test: replace some GNU-only code with more portable code that
              works on OS X.  Thanks Ryan Schmidt <ryandesign@macports.org>.

              makeman: deal properly with backlash in source.  But something
              was wrong with this change and it caused the program always to
              fail, so we reversed this change in 10.72.

              Build: don't build and install libjbig and libjasper if we
              are using external versions of them instead.

              Build: various cross-compile fixes, especially for MinGW.

              Build: work around bug in GCC < 4.2 related to SSE2 builtins
              that causes compile of pamflip to fail.

              Build: fix 'make package' where config.mk sets a subdirectory
              other than 'man' for the manual.

              Build: improve pointer man page text.

              <michael@moria.de>.

              giftopnm: Fix bug: crashes if purported GIF has neither a global
              color map nor a local one.

              pgmmorphconv: fix bug: always produces PGM Plain format.  Always
              present (progam was added to Netpbm in Release 10.0 (June 2002)).

              pamtilt: fix bug: unconditional crash.  Broken in Netpbm 10.63
              (June 2013).

              pnmgamma -srgbtobt709, -bt709tosrgb: fix bug; incorrect output
              nearly always.  Always broken (These options were new in
              Netpbm 10.32 (February 2006)).

              pamtosvg: fix use of unset variable; probably results in a
              crash.  Always present (pamtosvg was new in Netpbm 10.33 (March
              2006)).

              cameratopam: fix bug: variable used before set; unknown impact.
              Introduced in Netpbm 10.66 (March 2014).

              On Windows, don't leave temporary files around (previous code
              did so because unlink of an open file fails in Windows; new
              code deletes temporary files via atexit).  Thanks
              Ludolf Holzheid <ludolf.holzheid@gmx.de>.

              Libnetpbm: fix external header file pm.h so it does not include

              10.69 (December 2014).

              build: fix incompatible type compilation error in giftopnm.
              Introduced in Netpbm 10.38 (March 2007) (but obviously manifests
              only in recent build environments).

              build: fix compile failure in wordint_access_be.h with Bigendian
              target platforms.  Introduced in Netpbm 10.63 (June 2013).

              TRUE redefined.  Introduced in Netpbm 10.69 (December 2014).

14.12.25 BJH  Release 10.69.00

              pnmnorm: add -bsingle, -wsingle.

              Akira F Urushibata <afu@wta.att.ne.jp>.

              pamcrater: Add -verbose.

              ppmtoarbtxt: Fail if a #() escape sequence runs off end of
              file or is too long to process; before, the program would
              treat the text from # to EOF or where the buffer filled up
              as literal text, even ignoring any #() within.

              NetBSD: show actual numbers in messages instead of "f" or
              no information, by using NetBSD's vasprintf.

              Make %g in messages display the actual number instead of "g" in
              messages where platform doesn't have vasprintf.  (But scores of
              %f are still left).

              anytopnm: convert all images in a multi-image GIF instead of
              just the first.
              
              Improve "bad magic number" message from pbmXXX, and pgmXXX, and
              pnmXXX programs.

              Fix bogus message from ppmXXX programs when the input is not
              (per the magic number) a Netpbm image.  Introduced after
              Netpbm 10.26 (January 2005) but before Netpbm 10.35 (August
              2006).

              ppmtoarbtxt: Fix some undefined behavior when program limits
              are exceeded (i.e. buffer overruns).

              pambackground: fix bug: segfault or incorrect results in most
              cases.  Thanks Ludolf Holzheid (ludolf.holzheid@gmx.de).
              Introduced in Netpbm 10.37 (December 2006).

              Windows build: fix universal build failure with "No rule to make
              ...icon.netpbm.oLINKERISCOMPILER...".  Broken in Netpbm 10.67
              (June 2014).

14.09.26 BJH  Release 10.68.00

              Split pgmcrater into pamcrater and pamshadedrelief.

              pnmconvol: add -bias .

              Remove pnmcomp, install a pnmcomp symlink for pamcomp.

              Fix incorrect option parsing when there are multiple common
              options (e.g. -plain -quiet).  Always broken.  (Possibility of
              specifying multiple common options that don't cause the program
              to ignore every other option (like -version) was new in Netpbm
