The code was for C++, and suffers from bitrot (I don't think it was
ever intended to work with C, but I well could be wrong).

However, if someone wanted to work on this, then now would be a great
time to start: Mark Mitchell has been making changes to the C++ front
end which should make this much easier, and has been documenting the
necessary stuff, too (in gcc/cp/ir.texi).
