But tinycc is not supposed to support all bells and whistles from other 
compilers, much less assemblers.  Simply use GNU as for compiling 
your .S files from that old kernel.  You can still use tinycc for what it 
was designed: compiling C files.

Remember tokes between the directives (instead of parsing them) and repeat 
the parsing loop N times with that token list at .endr, for instance.
