# This file provides the language dependent support in the main Makefile.
# Each language makefile fragment must provide the following targets:
#
# foo.all.build, foo.all.cross, foo.start.encap, foo.rest.encap,
# foo.info, foo.dvi,
# foo.install-normal, foo.install-common, foo.install-info, foo.install-man,
# foo.uninstall, foo.distdir,
# foo.mostlyclean, foo.clean, foo.distclean, foo.extraclean, foo.realclean,
# 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: g++)
# - the compiler proper (eg: f771)
# - define the names for selecting the language in LANGUAGES.
# Extra flags to pass to recursive makes (and to sub-configure).
# Use different quoting rules compared with FLAGS_TO_PASS so we can use
# this to set environment variables as well
# Note that GCC_FOR_TARGET, GCC_FLAGS aren't in here -- treated separately.
