# Sequent Dynix/Ptx v. 4 hints
# Created 1996/03/15 by Brad Howerter, bhower@wgc.woodward.com
# Modified 1998/11/10 by Martin J. Bligh, mbligh@sequent.com
# to incorporate work done by Kurtis D. Rader & myself.
# Use Configure -Dcc=gcc to use gcc.
# cc wants -G for dynamic loading
lddlflags='-G'
# Remove inet to avoid this error in Configure, which causes Configure
# to be unable to figure out return types:
# dynamic linker: ./ssize: can't find libinet.so,
# link with -lsocket instead of -linet
libswanted=`echo $libswanted | sed -e 's/ inet / /'`
# Configure defaults to usenm='y', which doesn't work very well
usenm='n'
# for performance, apparently this makes a huge difference (~krader)
d_vfork='define'
optimize='-Wc,-O3 -W0,-xstring'
# We override d_socket because it's very hard for Configure to get it right
# in Dynix/Ptx, for several reasons.
# (1) the socket interface is in libsocket.so -- this wouldn't be so hard
# for Configure to fathom...but it gets more tangled.
# (2) if the system has been patched there can be libsocket.so.1.FOO.BAR,
# the FOO.BAR being the old version of the system before the patching.
# Configure picks up the old broken version.
# (3) libsocket.so points to either libsocket.so.1 (v4.2)
# or libsocket.so.1.1 (v4.4) The socket call in libsocket.so.1.1
# (BSD socket library) is called bsd_socket(), and has a macro wrapper
# to hide this.
# This information kindly provided by Martin J. Bligh of Sequent.
# As he puts it:
# "Sequent has unusual capabilities, taking it above and beyond
# the complexity of any other vendor" :-)
