gcc 4.5.0 stddef.h clobbers __size_t with #define, breaks VMS (code already
avoids similar on FreeBSD)‏
VMS decc$types.h:
typedef unsigned int __size_t;
but with GCC 4.5.0 this preprocesses as:
typedef unsigned int ;
and there are ensuing errors e.g. when compiling gcc/libiberty/regex.c
probably because of:
/usr/local/lib/gcc/alpha-dec-vms/4_5_0/include/stddef.h (it does get included)
#if defined (__FreeBSD__) && (__FreeBSD__>= 5)
/* __size_t is a typedef on FreeBSD 5!, must not trash it. */
#else
#define __size_t
#endif
presumably should be more like:
#if (defined (__FreeBSD__) && (__FreeBSD__>= 5)) || defined(__vms)
/* __size_t is a typedef on FreeBSD 5 and VMS, must not trash it! */
#else
#define __size_t
#endif

------- Comment #1 from jay dot krell at cornell dot edu 2010-05-10 23:01 -------
ps:
#if (defined (__FreeBSD__) && (__FreeBSD__>= 5)) || defined(__vms)
can probably just be:
#if __FreeBSD__>= 5 || defined(__vms)
or:
#if __FreeBSD__ | __vms
assuming the #define can also be be ommited on FreeBSD < 5, or that FreeBSD < 5
isn't supported, and depending on undefined to evaluate to 0.
