Ok, except it isn't really a C file. It's assembly intended to be
preprocessed by the C preprocessor (as is indicated by the .S extension).
I think the preprocessor will reduce the source to very little in case
NO_ASM is defined (but you didn't attach enough files for me to tell
for sure).

I therefore think the 'compile' script I referred to earlier may
handle your case; it will preprocess the .S file and feed the remaining
few bits to ml which in turn will do nothing, hopefully. But maybe ml
will miss an END directive? Or something? Untested...

Cheers,
Peter
