# The makefile built from this file lives in the language subdirectory.
# It's purpose is to provide support for:
#
# 1) recursion where necessary, and only then (building .o's), and
# 2) building and debugging cc1 from the language subdirectory, and
# 3) nothing else.
#
# The parent makefile handles all other chores, with help from the
# language makefile fragment, of course.
#
# The targets for external use are:
# all, TAGS, ???mostlyclean, ???clean.
