--- Comment #3 from Eric Reischer <emr-gnu at hev dot psu.edu> ---
No, it used gnatmake -P <gpr file>.

Is there a new recommended way to get gnatlink to generate a 32-bit bind file
and link object on MULTIARCH systems (x86/x86_64 in this specific case)?  It
seems this would be functionality that would be needed by others, as well as
needing a way to cross-compile for target hardware.
