 but I don't see where you're copying that. (I might have missed it. If
 you're not getting errors on fxc2 it must be working.)

 the build passes and I'd suspect compile time issues if that were a
 problem.

 No, from my recollection it will compile fine but won't run if the dll is
 missing from the directory.  (However if firefox builds, then fxc2 didn't
 error and it worked...)

 I suspect you do generate them; but without setting MOZ_COPY_PDBs they are
 not winding up next to the outputed files so they're not winding up in the
 final tarball. You could stick that into the mozconfig and see if they
 show up though.
