Oh bloody hell.

I figured -x c++ should have worked *FOR THE PREPROCESSOR*... dropping 
it should be fine, too, unless gcc is really really old.  This is 
probably a case for using $(cc_option) or something.

-x assembler-with-cpp is liable to have platform-specific bugs, since 
assembly comment syntax varies by platform.
