-# AIX 4.1 pthreading by Christopher Chan-Nui <channui@austin.ibm.com> and

# Contact dfavor@corridor.com for any of the following:
#
# - AIX 43x and above support
# - gcc + threads support
# - socks support
#
-# Apr 99 changes:
-#
-# - use nm in AIX 43x and above
-# - gcc + threads now builds
-# [(added support for socks) Jul 99 SOCKS support rewritten]
-#
# Notes:
