I think you misunderstood too - not hard as you were still packing up
when we had discussion ;-)

Given that PI (or whatever) is writing out the to-be-cc-ed C code
adding a bit here and there; it may as well s/foo/PL_foo/ or even
s/foo/(*(*PLinterp->vtable.foo()))/ or whatever the current flavour 
of the month is for the result off CPPing with generated embed.h.

Then there is no CPP messiness in the C code so no name clashes.

Think of it as a bit like C-front C++ compiler.
