* time/strftime.c (my_localtime_r): Define if ! HAVE_LOCALTIME_R,
and #define localtime_r to it. If _LIBC, use __localtime_r instead.
(my_gmtime_r): Similar, except it's not needed if ! HAVE_TM_GMTOFF.
* crypt/Makefile: Include Makeconfig and add crypt object dir to
rpath-link so that running the check finds the new library.
* crypt/cert.c: provide correct prototypes to prevent warnings.
Reported by Andreas Jaeger.
* sysdeps/mach/hurd/Makefile (rpath-link): Don't use += because
old and new value must be glued using `:'.
