23# This file provides the language dependent support in the main Makefile.
24# Each language makefile fragment must provide the following targets:
25#
26# foo.all.cross, foo.start.encap, foo.rest.encap,
27# foo.install-common, foo.install-man, foo.install-info, foo.install-pdf,
28# foo.install-html, foo.info, foo.dvi, foo.pdf, foo.html, foo.uninstall,
29# foo.mostlyclean, foo.clean, foo.distclean,
30# foo.maintainer-clean, foo.stage1, foo.stage2, foo.stage3, foo.stage4
31#
32# where `foo' is the name of the language.
33#
34# It should also provide rules for:
35#
36# - making any compiler driver (eg: gfortran)
37# - the compiler proper (eg: f951)
38# - define the names for selecting the language in LANGUAGES.
39# $(srcdir) must be set to the gcc/ source directory (*not* gcc/fortran/).
