- # 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.
