Packaging GDC

[Marc Schütz via D.gnu]

Hi!

I'm working on packaging GDC for openSUSE, and I have a few 
questions.

Is it possible to make the build process install only D related 
files, for example cc1d, but not cc1?

If the above works (or I manually exclude generic GCC files from 
the package), will the D specific binaries be compatible with 
generic GCC binaries/libs from other GCC versions?

I'm asking this because I'd rather not have to make the GDC 
package depend on the distribution's default GCC packages, 
because then I would have to match the GCC versions across the 
different openSUSE versions...

Any hints?
