but a commit mail got lost, it's the same as for this commit:
lib/libc/gen confstr.c crypt.c disklabel.c fstab.c getcap.c
getgrent.c getgrouplist.c getpass.c getpwent.c
initgroups.c nlist.c psignal.c pwcache.c setmode.c
sleep.c sysconf.c sysctl.c syslog.c usleep.c
lib/libc/locale none.c read_runemagi.c setlocale.c
lib/libc/net gethostbydns.c getnetbydns.c getnetbynis.c
lib/libc/nls msgcat.c
lib/libc/quad Makefile.inc
lib/libc/regex engine.c regcomp.c regerror.c
Minor cleanup, mostly unused vars and missing #includes.
Limit the number of quad functions we pull in for 'i386'.
I still belive the quad stuff should go back into gcc.
Add compile-time warnings about crypt functions.
