Do you have a pointer to the discussion of this feature?  I read the
explanation in install.texi, and I don't really see why the user can't
just make a new --prefix for this case.  But I'd like to read the
original discussion instead of going over the arguments again...

Do we really need this?  This isn't really an ordinary configure
check.

Is this correct for multilibs when srcdir==objdir?
I think you need $libgcj_basedir/../gcc/version.c here.
See the comments in LIBGCJ_CONFIGURE in acinclude.m4.

Otherwise this looks fine.
BTW does it need a tweak for header file installation?
