[Bug c/44279] New: system.h calloc/malloc/realloc VMS size_t vs. __size_t

[jay dot krell at cornell dot edu]

VMS has:
    typedef long unsigned int size_t;
    typedef unsigned int __size_t;
    void * calloc (__size_t __nmemb, __size_t __size);
    void * malloc (__size_t __size);
    void * realloc (__void_ptr64 __ptr, __size_t __size);

possibly this is something for fixincludes to deal with.

As a result, gcc/system.h gets warnings/errors here, due to varying
declarations of malloc/calloc/realloc (size_t vs. __size_t, unsigned vs.
unsigned long):

#if defined (HAVE_DECL_MALLOC) && !HAVE_DECL_MALLOC
extern void *malloc (size_t);
#endif

#if defined (HAVE_DECL_CALLOC) && !HAVE_DECL_CALLOC
extern void *calloc (size_t, size_t);
#endif

#if defined (HAVE_DECL_REALLOC) && !HAVE_DECL_REALLOC
extern void *realloc (void *, size_t);
#endif


I changed mine to:

#if defined (HAVE_DECL_MALLOC) && !HAVE_DECL_MALLOC && !defined(__vms)
extern void *malloc (size_t);
#endif

#if defined (HAVE_DECL_CALLOC) && !HAVE_DECL_CALLOC && !defined(__vms)
extern void *calloc (size_t, size_t);
#endif

#if defined (HAVE_DECL_REALLOC) && !HAVE_DECL_REALLOC && !defined(__vms)
extern void *realloc (void *, size_t);
#endif


perhaps not the best fix.
