Make libf2c a shared library (gcc/f directory).

2001-09-29  Juergen Pfeifer  <juergen.pfeifer@gmx.net>

	Make libf2c a shared library (gcc/f directory).

	* Make-lang.in: Pass define of frtbegin.o to compilation of g77spec.c.
	* g77spec.c (lang_specific_driver): Treat linking in of frtbegin.o.

            Toon Moene  <toon@moene.indiv.nluug.nl>

	Make libf2c a shared library (libf2c directory).

	* aclocal.m4: Get definition of libtool.
	* Makefile.in: Use libtool.
	* configure.in: Use libtool.
	* configure: Regenerated.
	* libF77/Makefile.in: Use libtool; treat main program contained in
	libF77/main.c specially.
	* libF77/configure.in: Use libtool.
	* libF77/configure: Regenerated.
	* libI77/Makefile.in: Use libtool.
	* libI77/configure.in: Use libtool.
	* libI77/configure: Regenerated.
	* libU77/Makefile.in: Use libtool.
	* libU77/configure.in: Use libtool.
	* libU77/configure: Regenerated.
	* libU77/date_.c: Adapt for -fPIC compiling.
	* libU77/vxtidate_.c: Ditto.
