# Note: We're fooling Makefile.rules here. The sources listed don't exist but
# it doesn't matter. Makefile.rules just uses $(SOURCES) to generate the set of
# 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 
# each of those bytecode objects from the sources we do have in this directory.
