description:
When calling 'cc -c' use a stripped down version of CFLAGS that
removes all -Wl,* entries.  Otherwise some versions of gcc will
give a warning which in turn breaks the autoconf check for fortran
libraries.  This fixes at least cad/tnt-mmtl and probably any
other package that uses the AC_F77_LIBRARY_LDFLAGS autoconf macro.

Bump rev to f2c-20001205nb10.
