This is an easy kind of thing to fix.

 jbook2:gcc.3 jay$ grep vms_c_register_includes /src/gcc-4.7.2/gcc/config/*/*

I think this target_c_incpath doesn't belong in a language-independent file.
or vms_c_register_includes should be in a language-independent file.
or link all the frontends into one executable.


This is likely fixed in versions.
Recording here for either posterity, or to fix in 4.7.newer, or for
people searching the bug database, though anyone trying this target
will probably have any problems and know how to figure this out.


Oh, drat, there is 4.7.3. I can check it.
