bootstrap failure alphaev6-dec-osf5.0 (struct exception redefinition)

[Andrew Hobson <ahobson at eng dot mindspring dot net>]

I updated CVS on July 12 at around 11:00 ET using the
contrib/gcc_update script.

I saw a message in the archives from last year about a similar error
occuring on Solaris, but it wasn't during a bootstrap.
