# 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

usenm='n'

# for performance, apparently this makes a huge difference (~krader)

# 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" :-)
