It +# was originally developed with version 5.4.3.10 of the OS, and then was +# later updated running under version 4.11.2 (running on m88k hardware). +# The gross features should work with versions going back to 2.nil but +# some tweaking will probably be necessary. +# +# DGUX is an SVR4 derivative. It ships with gcc as the standard +# compiler. Since version 3.0 it has shipped with Perl 4.036 +# installed in /usr/bin, which is kind of neat. Be careful when you +# install that you don't overwrite the system version, though (by +# answering yes to the question about installing perl as /usr/bin/perl), +# as it would suck to try to get support if the vendor learned that you +# were physically replacing the system binaries. +# +# -Roderick Schertler <roderick@argon.org> + +# The standard system compiler is gcc, but invoking it as cc changes its +# behavior. I have to pick one name or the other so I can get the +# dynamic loading switches right (they vary depending on this). I'm +# picking gcc because there's no way to get at the optimization options +# and so on when you call it cc. + +########################################## +# Modified by Takis Psarogiannakopoulos +# Universirty of Cambridge +# Centre for Mathematical Sciences +# Department of Pure Mathematics +# Wilberforce road +# Cambridge CB3 0WB , UK +# e-mail <takis@XFree86.Org> +# Use GCC-2.95.2/3 rev (DG/UX) for threads +# This compiler supports the -pthread switch +# to link correctly DG/UX 's -lthread. +# March 2002 +########################################### + +cc=gcc +ccflags="-DDGUX -D_DGUX_SOURCE" +# Debug build.
