--- Comment #2 from Christian Persch (GNOME) <c...@gnome.org> --- According to the comment this is needed for mkstemp and ftruncate, but it didn't actually cause a problem when compiling on my machine. I noticed the problem when I tried to add code for bug https://bugs.exim.org/show_bug.cgi?id=2010 which needed _GNU_SOURCE which I tried unsuccessfully to add in the same place. The way these feature level defines work is that the absolutely need to be defined before the first libc header is included. I think replacing this explicit define with using AC_USE_SYSTEM_EXTENSIONS in configure.ac should work and be the simplest fix. -- You are receiving this mail because: You are on the CC list for the bug. -- ## List details at https://lists.exim.org/mailman/listinfo/pcre-dev
