Gnulib's emulation of mkostemp doesn't have races that Emacs's does. * configure.ac (mkostemp): Remove check for this function; gnulib does the check now. (mkstemp): Remove check for this no-longer-used function. * lib/mkostemp.c, lib/secure_getenv.c, lib/tempname.c, lib/tempname.h: * m4/mkostemp.m4, m4/secure_getenv.m4, m4/tempname.m4: New files, copied from Gnulib. * lib/gnulib.mk, m4/gnulib-comp.m4: Regenerate. * admin/merge-gnulib (GNULIB_MODULES): Add mkostemp. * lib-src/movemail.c (main): * lib-src/update-game-score.c (write_scores): Use mkostemp (which now works on all platforms, due to changes in the portability layer) rather than mktemp (which has a race) or mkstemp (which we no longer bother with). * src/callproc.c (create_temp_file): * src/filelock.c (create_lock_file): Assume mkostemp, since it's now provided by Gnulib.
