+ mktime: prefer C23 style overflow checking
+ Prefer stdckdint.h macros to intprops.h macros where either will do,
+ as this is the C23 standard. Also, it ports around a pcc bug.
+ * config/srclist.txt: Comment out mktime.c.
+ * lib/mktime.c: Include stdckdint.h, not intprops.h.
+ (__mktime_internal): Prefer stdckdint.h to intprops.h macros.
+ * modules/mktime (Depends-on): Add stdckdint.
+
limits-h: port to pcc
* doc/posix-headers/limits.texi: Document the issue.
* lib/limits.in.h (MB_LEN_MAX): New macro, if not already defined.
