The offending file is event32.c or something like that.  The solution I used
was to add an intermediate step in the makefile.
.c.S:
	gcc -S ......
	
.S.o:
	gcc -c ...... file.S
	
using capital S as the file extension tells gcc to run the file through cpp
when assembling, thus stripping the comments.
I think the reason for this problem is that GCC has changed behaviour in
this respect since GRX was last updated.

The makefiles are written for Turbo make sometime after Turbo C v2.0, as
the Turbo Pascal 6 make works fine, but the TC2 one doesn't.
