malloc protoype in egcs

[H.J. Lu]

In my current prototyping patch, I used

extern GENERIC_PTR xmalloc              PROTO((unsigned));
extern GENERIC_PTR xrealloc             PROTO((GENERIC_PTR, unsigned));
extern GENERIC_PTR xcalloc              PROTO((unsigned, unsigned));

The reasons I used unsigned instead of ssize_t are

1. ssize_t may be available when building gcc.
2. ssize_t may not be correct for the malloc being used.

The drawback is "unsigned" may not be correct either. But we only
need to worry about it in the file where xmalloc/xrealloc/xcalloc
are defined. Unless it is worse than no prototype at all, which is
the case today, I think "unsigned" is a better choice.

Any ideas?

Thanks.
