        * configure.in: Extended the glibc regexp check and enabled
	substitution for Makefiles.

	* app/Makefile.am: Compile regexp only if not in glibc.

	* app/plug_in_cmds.c:
	* app/procedural_db_cmds.c:
	* app/regexrepl.c: Include the correct local headerfile
	if no new glibc with regexp is available.

	* app/regex.c:
	* app/regex.h: Moved into regexprepl.[ch] to avoid nameclashes.
