+
+ * MODULES.html.sh: Document tempname.
+ * modules/mkstemp (Depends-on): Add tempname, and drop transitive
+ dependencies.
+ (Files): Move lib/tempname.c...
+ * modules/tempname: ...to this new module.
+ * m4/mkstemp.m4 (gl_FUNC_MKSTEMP): Remove tempname checks.
+ (gl_PREREQ_TEMPNAME): Move...
+ * m4/tempname.m4: ...to this new file.
+ * lib/mkstemp.c (includes) [!_LIBC]: Use tempname.h.
+ * modules/sys_stat (Depends-on): Add stat-macros.
+ * lib/stat_.h (includes): Pick up stat macros.
+ * m4/sys_stat_h.m4 (gl_HEADER_SYS_STAT_H): Replace <sys/stat.h>
+ if stat macros are broken.
+ * lib/tempname.c (includes): No need to include "stat-macros.h".
+ (__gen_tempname) [!_LIBC]: Expose as gen_tempname.
+ (direxists, __path_search) [!_LIBC]: Don't compile these in
+ gnulib; the tmpdir module covers that.
+ * lib/tempname.h: New file.
+
