The behavior in 3.4 was a feature, IIRC not well documented one.

Well what happens when you do:

gcc -combine t.cc t.c -c -o t.o
We need an error but what should it be.  I think leaving out the -combine will
not confuse
people as they should be reading the documention anyways.

have_c is set for both -S and -c.
