I am trying to get pthreads to build on 2.0R. I have had a number of
problems, but this last one led me down a rat hole that seems to go
beyond pthreads. In one source file was :
#if !defined(_ANSI_SOURCE)
#define CLK_TCK 100
#endif /* not ANSI */
This resulted in redefinition of the value in <machine/limits.h>.
So I started to try to hunt down who defines _ANSI_SOURCE. I found it
referenced numerous times in places in the standard includes. But I
can't find anywhere that it is defined. The best gcc does is:
<~/code>> cc -E -dM -ansi foo.c
#define __STRICT_ANSI__ 1
#define __FreeBSD__ 2
#define __i386__ 1
#define __i386 1
#define __GNUC_MINOR__ 6
#define __unix 1
#define __unix__ 1
#define __GNUC__ 2
So is this the programmers responsibility to define?
