To add to this data: on i686-mingw the system gcc-3.4.5-20060117-3 is able to bootstrap SVN 4.4 with --enable-languages=c,ada the resulting compiler is able to compile simple Ada programs and ACATS is currently running (I can't test C because I don't have dejagnu - advice welcomed).
Current trunk fails to bootstrap but this is with C only so the issue is not Ada related.
