Hmm... trace the naming patch from the mangled declaration to a method. You
can drop into the build directory and run the gcc command by hand. Tinker
with it to add a -E and save the output (not -o...). That will let you see
the preprocessed output. Something specific and subtle is happening. Decode
that and you win.
