As I have not clearly mentioned it before, there exist the following
workarounds:

a) Make "dim" *not* PRIVATE. ("dim" can be marked as PROTECTED to avoid
unwanted changes.) That might be easier for the real world code than
concatenating files together.

b) Put MODULE ENERGY_FUNCTION into the same file as all the callers of its
functions. (For completeness.)

b) Compile "MODULE ENERGY_FUNCTION" with -O0.

c) Use GCC 4.7 and wait for the patch ;-)
