Unneeded compiler warning in glob.c

[Tim Rühsen]

Here is a patch to silence this warning:

glob.c: In function 'rpl_glob':
glob.c:618:64: warning: pointer of type 'void *' used in arithmetic
[-Wpointer-arith]
                       err = getpwnam_r (s.data, &pwbuf, s.data + ssize,


With Best Regards, Tim
