I will not do a fix on the GNAT GPL Edition, because the vote was
against it.  I will concentrate on GCC from the FSF.  I can't maintain
both.

AdaCore can integrate any patches I contribute to the FSF into GNAT
GPL Edition by dropping the special exception, as allowed specifically
by the GMGPL and the GPL.

Agreed.  Patching the GNAT GPL Edition might make it impossible to
port patches to the FSF branch (because this would require granting
the special exception).  The other way around (revoking the special
exception) is always possible, therefore patches should be made
against the FSF tree.
