28# We override d_socket because it's very hard for Configure to get it right
29# in Dynix/Ptx, for several reasons.
30# (1) the socket interface is in libsocket.so -- this wouldn't be so hard
31# for Configure to fathom...but it gets more tangled.
32# (2) if the system has been patched there can be libsocket.so.1.FOO.BAR,
33# the FOO.BAR being the old version of the system before the patching.
34# Configure picks up the old broken version.
35# (3) libsocket.so points to either libsocket.so.1 (v4.2)
36# or libsocket.so.1.1 (v4.4) The socket call in libsocket.so.1.1
37# (BSD socket library) is called bsd_socket(), and has a macro wrapper
38# to hide this.
39# This information kindly provided by Martin J. Bligh of Sequent.
40# As he puts it:
41# "Sequent has unusual capabilities, taking it above and beyond
42# the complexity of any other vendor" :-)
