# TEA_TCL_LINK_LIBS
#
# Search for the libraries needed to link the Tcl shell.
# Things like the math library (-lm) and socket stuff (-lsocket vs.
# -lnsl) are dealt with here.
#
# Arguments:
# Requires the following vars to be set in the Makefile:
# DL_LIBS (not in TEA, only needed in core)
# LIBS
# MATH_LIBS
#
# Results:
#
# Substitutes the following vars:
# TCL_LIBS
# MATH_LIBS
#
# Might append to the following vars:
# LIBS
#
# Might define the following vars:
# HAVE_NET_ERRNO_H

# right (and it must appear before "-lm").

# Check for the existence of the -lsocket and -lnsl libraries.
# The order here is important, so that they end up in the right
# order in the command line generated by make. Here are some
# special considerations:
# 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.
# 4. On some SVR4 systems, can't use -lsocket without -lnsl too.
# To get around this problem, check for both libraries together
# if -lsocket doesn't work by itself.
