[21.1] Patch for mips-sony-bsd (Sony NEWS-OS 4.2R)

[NAKAJI Hiroyuki]

Hi,

I need attached change to build emacs-21.1 on my Sony NEWS-OS 4.2R
configured as mips-sony-bsd. It should be applied in emacs-21.1/src
directory.

The change for gmalloc.c is tricky. Because NEWS-OS 4.x is not fully
POSIX, malloc() functions are declared as 'char *malloc()' and so on.

According to malloc(3), these function's declareration is:

     char *malloc(size)
     unsigned size;

     free(ptr)
     char *ptr;

     char *realloc(ptr, size)
     char *ptr;
     unsigned size;

     char *calloc(nelem, elsize)
     unsigned nelem, elsize;

     char *alloca(size)
     int size;

This is not POSIX compatible, but gcc assumes the system should be POSIX
and there are conflicts against these functions.
