# 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: gcc)
# - the compiler proper (eg: cc1)
# - define the names for selecting the language in LANGUAGES.

#
# Define the names for selecting c in LANGUAGES.
c: cc1$(exeext)

# Tell GNU make to ignore these if they exist.
.PHONY: c gcc

# The C front end driver.  This is different from the drivers for other
# front ends, because there is no C language specific driver (i.e. nothing
# is to cc1 as e.g. g++ is to cc1plus, or gfortran is to f951).
