Hmm, one problem is that we need to know when we should pass -- on to cc1, etc.
also.  For an example:

gcc t.c -- -l.c

is that -l.c a c source or a library for ld to have at and how do we invoke ld
then:
with "-- -l.c" or just "-l.c"

It's a source file - everything after -- should be a source or object file 
according to the suffix.  -lfoo would mean that an object file called 
literally -lfoo is to be linked, not libfoo.a.  You could either pass -- 
to ld or change -lfoo to ./-lfoo.
