# This file provides the language dependent support in the main Makefile.
# Each language makefile fragment must provide the following targets:
#
# foo.all.cross, foo.start.encap, foo.rest.encap,
# foo.install-common, foo.install-man, foo.install-info, foo.install-pdf,
# foo.install-html, foo.info, foo.dvi, foo.pdf, foo.html, foo.uninstall,
# foo.mostlyclean, foo.clean, foo.distclean,
# foo.maintainer-clean, foo.stage1, foo.stage2, foo.stage3, foo.stage4
#
# where `foo' is the name of the language.
#
# It should also provide rules for:
#
# - making any compiler driver (eg: gfortran)
# - the compiler proper (eg: f951)
# - define the names for selecting the language in LANGUAGES.
# $(srcdir) must be set to the gcc/ source directory (*not* gcc/fortran/).
