Don't we require bootstrapping for cross-compilers? In that case the frontend
would still be built by the gcc from the same tree as the Fortran frontend.

If that's not the case, does your statement mean "gcc-compatible", or do we
have to support other build compilers as well? The issue raised in this thread
were variable length arrays in structures, which were supported as a gcc
extension before, IIRC.
