#	Set LEX.

#	specify a prefix other than `yy').  The -P flag was added at
#	the same time a -V (version) flag was added (version 2.4.1),
#	so if `flex' understands -V, it'll understand -P (checking
#	for -P directly requires a flex input file).
#
#	1. If `LEX' is not set, look for `flex' and set `LEX' to
#	   `flex' if found.
#	2. If `flex' was found, see if it understands -V.  If so,
#	   set `scanner_src' and `typer_src' to have `flex' generate
#	   the C files from the flex input files
#	   ascend4/compiler/scanner.l & ascend4/interface/typelex.l
#	   We don't need to look for libfl.a since we define
#	   yywrap() ourselves.
#	3. If `flex' wasn't found or was found but isn't new enough:
#	   a. Print a warning message
#	   b. Set `scanner_src' and `typer_src' to use pre-generated
#	      C files for the flex files mentioned in (2).

#--------------------------------------------------------------------
#	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.
#	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.

#--------------------------------------------------------------------
#	The following comes directly from the configure.in file for
#	Tcl8.0.
#
#	The statements below define a collection of symbols related to
#	dynamic loading and shared libraries:
#
#	DL_OBJS -	Name of the object file that implements dynamic
#			loading for ASCEND on this system.
#	DL_LIBS -	Library file(s) to include in tclsh and other base
#			applications in order for the "load" command to work.
#	LD_FLAGS -	Flags to pass to the compiler when linking object
#			files into an executable application binary such
#			as tclsh.
#	LD_SEARCH_FLAGS-Flags to pass to ld, such as "-R /usr/local/tcl/lib",
#			that tell the run-time dynamic linker where to look
#			for shared libraries such as libtcl.so.  Depends on
#			the variable LIB_RUNTIME_DIR in the Makefile.
#	MAKE_LIB -	Command to execute to build the ASCEND library;
#			differs depending on whether or not ASCEND is being
#			compiled as a shared library.
#	SHLIB_CFLAGS -	Flags to pass to cc when compiling the components
#			of a shared library (may request position-independent
#			code, among other things).
#	SHLIB_LD -	Base command to use for combining object files
#			into a shared library.
#	SHLIB_LD_LIBS -	Dependent libraries for the linker to scan when
#			creating shared libraries.  This symbol typically
#			goes at the end of the "ld" commands that build
#			shared libraries. The value of the symbol is
#			"${LIBS}" if all of the dependent libraries should
#			be specified when creating a shared library.  If
#			dependent libraries should not be specified (as on
#			SunOS 4.x, where they cause the link to fail, or in
#			general if ASCEND and Tk aren't themselves shared
#			libraries), then this symbol has an empty string
#			as its value.
#	SHLIB_SUFFIX -	Suffix to use for the names of dynamically loadable
#			extensions.  An empty string means we don't know how
#			to use shared libraries on this platform.
#	ASC_LIB_FILE -	Name of the file that contains the ASCEND library, such
#			as libtcl7.8.so or libtcl7.8.a.
#	ASC_LIB_SUFFIX -Specifies everything that comes after the "libtcl"
#			in the shared library name, using the $VERSION variable
#			to put the version in the right place.  This is used
#			by platforms that need non-standard library names.
#			Examples:  ${VERSION}.so.1.1 on NetBSD, since it needs
#			to have a version after the .so, and ${VERSION}.a
#			on AIX, since the ASCEND shared library needs to have
#			a .a extension whereas shared objects for loadable
#			extensions have a .so extension.  Defaults to
#			${VERSION}${SHLIB_SUFFIX}.
#--------------------------------------------------------------------

# Step 1: set the variable "system" to hold the name and version number
# for the system.  This can usually be done via the "uname" command, but
# there are a few systems, like Next, where this doesn't work.

# Changed this to use the "$host" variable from AC_CANONICAL_HOST

# Step 2: check for existence of -ldl library.  This is needed because
# Linux can use either -ldl or -ldld for dynamic loading.
