+
+ New module 'mkostemp'.
+ Based on Ulrich Drepper's 2007-08-10 change in glibc.
+ * lib/stdlib.in.h (mksotemp): New declaration.
+ * lib/mkostemp.c: New file, from glibc with modifications.
+ * lib/tempname.h (GT_FILE): Remove outdated comment.
+ (gen_tempname): Add flags argument.
+ * lib/tempname.c (__GT_BIGFILE): Remove macro.
+ (__GT_FILE): Map to 1.
+ (small_open, large_open): Remove macros.
+ (__gen_tempname): Add flags argument. Remove code for __GT_BIGFILE.
+ * lib/mkstemp.c (mkstemp): Update.
+ * lib/mkdtemp.c (mkdtemp): Likewise.
+ * m4/mkostemp.m4: New file.
+ * m4/stdlib_h.m4 (gl_STDLIB_H_DEFAULTS): Initialize GNULIB_MKOSTEMP,
+ HAVE_MKOSTEMP.
+ * modules/stdlib (Makefile.am): Substitute GNULIB_MKOSTEMP,
+ HAVE_MKOSTEMP.
+ * modules/mkostemp: New file, based on modules/mkstemp.
+ * doc/glibc-functions/mkostemp.texi: Mention the new module.
+ * NEWS: Mention the change.
