175 * As of version 2.46, glib thinks the Windows compiler where
176 * _MSC_VER >= 1400 can handle G_HAVE_ISO_VARARGS. This makes our
177 * magic macros wrapping their macros fail in the simplest case,
178 * where only the fmt arg is present (eg vm_debug("test").
179 * vm_debug("test %d", 123) works fine.
180 *
181 * Work around this by making g_debug() et all be inline functions,
182 * which is how it works if G_HAVE_ISO_VARARGS isn't set.
183 *
184 * Though experimentation we found that this also works:
185 *
186 * #define LOGHELPER(...) ,##_VA_ARGS__
187 * #define LOG(fmt, ...) g_debug_macro(__FUNCTION__, ": " fmt, LOGHELPER(__VA_ARGS__))
188 *
189 * but since its disgusting and even more magical, the inline variant was chosen
190 * instead.
