Is this an "approved" fix?  have you sent it to the egcs folks?

If these are in egcs, please report this to that list.  An egcs release is
approaching.

haven't we heard this problem before ... hmmmm...

Cut and pate the failing command.  Add -M to it and save the dependency

another installation mixed in.

If you have any gcc or gnat environment variables set, it could be causing
problems.
