# The makefile built from this file lives in the language subdirectory.
# Its purpose is to provide support for:
#
# 1) recursion where necessary, and only then (building .o's), and
# 2) building and debugging f771 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.

#Build the first part of this list with the command line:

#Note that this command uses the host C compiler;
# use HOST_CC="./xgcc -B./" to use GCC in the build directory, for example.
#Also note that this particular build file seems to want to use
# substitions: $(CONFIG_H) for config.h; $(TREE_H) for tree.h;
# $(RTL_H) for rtl.h; etc..  deps-kinda uses a sed script to do those
# substitutions, plus others for elegance.
