Now I'm confused...or is the patch reverted? It said:
-       ctime_r(&now, nowstr, 26);
+       ctime_r(&now, nowstr);

This has got nothing to do with GCC, it's only related to system headers.
Quoth SunOS 5.9:

     #include <time.h>
     char *ctime_r(const time_t *clock, char *buf, int buflen);
     cc [ flag... ] file... -D_POSIX_PTHREAD_SEMANTICS [ library... ]
     char *ctime_r(const time_t *clock, char *buf);

>From my understanding of the patch above (*removing* the 3rd arg), I assumed
that -D_POSIX_PTHREAD_SEMANTICS was set. It should probably be set like
somewhere else (in libraries/bases/cbits/dirUtils.c), but I strongly suggest
not doing this in the same (ie. through #define), but rather indeed setting it
as a compiler flag. Otherwise, one of those days we'll get bitten by compiling
something with skewed headers. Due to the plethora of variables in rts/Makefile,
I'm a bit at a loss where to stick this in.
