:-)  Try Tornado 2.0.  It is newer and supports exceptions.  It is an
egcs 1.0.3 era C++ compiler.

The intent is to allow a user to compile up egcs and it should just
work, including exceptions.  It will take a little bit of work, as not
all the pieces were in 1.1.2, but the patch set I mailed out today
should have most of the bits in it (but not all of them).

Depends on how skillful you are or how much you want it to work.  I
was hoping that most all the bits were in my patch set.

They should mix well.  If they don't, that's a bug.
