Hi,
 	What I've done is replace the generating command for scmos.tech in 
scmos/Makefile (gcc ...) with "cpp -traditional -P", somehow the old 
options being passed to "gcc ..." were incorrect.  I don't remember if 
"gcc -E ..." (-E means preprocess-only) works, but I didn't see any 
reason to invoke gcc if only the preprocessor was used.  (This predates 
magic 7.1.)
