# An explanation is in order for the strange things going on with the
# various LIBS. There are three separate definitions for LIBS. The
# reason is that some systems require shared libraries include
# references to their dependent libraries, i.e., any additional
# libraries that must be linked to. And some systems get upset if the
# references are repeated on the link line. So therefore, we create
# one for Expect, one for Expect and Tcl, and one for building Expect's own
# shared library. Tcl's tclConfig.sh insists that any shared libs
# that it "helps" build must pass the libraries as LIBS (see comment
# near end of this configure file). I would do but since we're close
# to hitting config's max symbols, we take one short cut and pack the
# LIBS into EXP_SHLIB_LD_LIBS (which is basically what Tcl wants to do
# for us). The point, however, is that there's no separate LIBS or
# EXP_LIBS symbol passed out of configure. One additional point for
# confusion is that LIBS is what configure uses to do all library
# tests, so we have to swap definitions of LIBS periodically. When we
# are swapping out the one for Expect's shared library, we save it in
# EXP_LIBS. Sigh.
