-# Note: We're fooling Makefile.rules here. The sources listed don't exist but

-# object files to put in the library. Since we've specified BYTECODE_LIBRARY
-# above, it changes the .c suffix to .bc suffix. Below are rules to build

+# 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.
