# Note: We're using FAKE_SOURCES because the comp_*.c don't really exist.
# However this makefile builds comp_*.bc and that's what we want in the library.
# The FAKE_SOURCES variable supports this kind of construction. It uses the
# FAKE_SOURCES to determine a list of things to build, but doesn't use 
# FAKE_SOURCES for dependencies, distribution, etc. It is assumed the makefile
# will know how to build the objects eventhough the sources don't exist.
