SCO remove() and unlink()

[Kevin Steves]

There was a patch merged in on 9/29 that changed remove() calls to
unlink():

 - (djm) Merged big SCO portability patch from Tim Rice
   <tim at multitalents.net>

Does SCO's libc not include remove()?  Note that sftp-server.c is
currently using remove.  The reason I ask is I'd like to keep the
portable tree as close to openbsd as possible, and if we need remove()
for SCO we should add a bsd-remove.c or something.
