(Instead of "== NULL" in line 16 where u do getpwnam should'nt it be "!="
?)  Warnings must be compiler dependent. On SunOS v4.1.3, using "cc" it
gives the same warning which u got, but compiled. But using "gcc" (ver
2.7.2.2), got compiled w/o warning.

ftp://prep.ai.mit.edu/pub/gnu/ sources for the likes of "cp" can b found
under fileutils.. If you want sources for crypt, you can't legally d/l
from US sites, but these sites always have a pointer to some non US sites.
