I reported this one a couple of months back, but sadly it still 
doesn't seem to have been fixed.

I did work around it by compiling in C++ mode, though, although it 
required adding a lot of extern "C" blocks.  But really the 
codegen templates need to get fixed.  Or we need to get another 
code-insertion block that inserts at the top of the generated 
function instead of further down.
