# hints file for BSD/OS (adapted from bsd386.sh)
# Original by Neil Bowers <neilb@khoros.unm.edu>; Tue Oct  4 12:01:34 EDT 1994
# Updated by Tony Sanders <sanders@bsdi.com>; Sat Aug 23 12:47:45 MDT 1997
#     Added 3.1 with ELF dynamic libraries (NOT in 3.1 yet.
#     Estimated for 4.0) SYSV IPC tested Ok so I re-enabled.
#
# Updated to work in post-4.0 by Todd C. Miller <millert@openbsd.org>
#
# Updated for threads by "Timur I. Bakeyev" <bsdi@listserv.bat.ru>
#
# To override the compiler on the command line:
#     ./Configure -Dcc=gcc2
#
# The BSD/OS distribution is built with:
#     ./Configure -des -Dbsdos_distribution=defined
