# 1. If the X library binaries are in a non-standard directory,

# 2. On systems such as AIX and Ultrix that use "-L" as the
# search path option, colons cannot be used to separate
# directories from each other. Change colons to " -L".
# 3. Create two sets of search flags, one for use in cc lines
# and the other for when the linker is invoked directly. In
# the second case, '-Wl,' must be stripped off and commas must
# be replaced by spaces.

# Check for the existence of various libraries. The order here
# is important, so that then end up in the right order in the
# command line generated by make. The -lsocket and -lnsl libraries
# require a couple of special tricks:
# 1. Use "connect" and "accept" to check for -lsocket, and
# "gethostbyname" to check for -lnsl.
# 2. Use each function name only once: can't redo a check because
# autoconf caches the results of the last check and won't redo it.
# 3. Use -lnsl and -lsocket only if they supply procedures that
# aren't already present in the normal libraries. This is because
# IRIX 5.2 has libraries, but they aren't needed and they're
# bogus: they goof up name resolution if used.
