I need to construct a preprocessor scaffolding which will
generate code at the beginning of main() to call once
each function defined in the program.  I do not know anything
about the functions except that I need an array of pointers
by which to call the functions.  The scaffolding should
either provide this array of pointers initialized, or provide
the code to call each function once.  The scaffolding needs to
be resiliant enough such that if I add a function, without
doing anything more than include a macro in the function, a
pointer to this new function gets put into the array during
the next compile.

Can such a beast be created? cpp or m4 are both fine.
Any pointers?

Thanks.
