memcmp.c needs intptr_t

[O.Sezer]

Hello:  Found this while compiling gdb for win64: memcmp.c
casts long to pointers but sizeof(long) == 4 for win64. A patch
is attached here.  (if it gets applied, does it automatically go
into gdb and/or any other users?)

Regards,
Ozkan Sezer

PS:  There are a few similar errors of long type in libiberty,
as it appears in binutils and gcc, too, specifically in md5.h
(uintptr_t type definition) and in hashtab.c (in hash_pointer() ).
Where should the patches be sent to?
