21: # It's purpose is to provide support for:
22: #
23: # 1) recursion where necessary, and only then (building .o's), and
24: # 2) building and debugging cc1 from the language subdirectory, and
25: # 3) nothing else.

27: # The parent makefile handles all other chores, with help from the
28: # language makefile fragment, of course.
