Win32 hacks from <Rob_Tulloh@tivoli.com>.
* posix/glob.c [WIN32]: Don't include <pwd.h>; don't use d_ino;
use void * for my_realloc; include <malloc.h> for alloca.
(glob) [WIN32]: Use "c:/users/default" for ~ if no HOME variable.
* posix/fnmatch.h [WIN32]: Use prototypes even if [!__STDC__].
* posix/glob.h: Likewise.
