You're right, but it does not compile without the 3rd argument! Maybe
this is due to gcc_4.0.3_s10 ? Should one simply rely on ctime?
From my understanding of the patch above (*removing* the 3rd arg), I assumed
Now I'm confused...or is the patch reverted? It said:
#if HAVE_CTIME_R
- ctime_r(&now, nowstr, 26);
+ ctime_r(&now, nowstr);
#else
This has got nothing to do with GCC, it's only related to system headers.
Quoth SunOS 5.9:
SYNOPSIS
#include
char *ctime_r(const time_t *clock, char *buf, int buflen);
...
POSIX
cc [ flag... ] file... -D_POSIX_PTHREAD_SEMANTICS [ library... ]
char *ctime_r(const time_t *clock, char *buf);
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.
