# 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 and Tk (EXP_AND_TK_LIBS), one for Expect and Tcl
# (EXP_AND_TCL_LIBS), and finally, 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 peridically.  When we
# are swapping out the one for Expect's shared library, we save it in
# EXP_LIBS.  Sigh.
