OK, multiple exception handling mechanisms. I became 'at odds with helpfulness'
somewhere around comment #21. I only used that Option since OpenBSD Ports
had used it (and without quoting OpenBSD source, and their license, they
seem to use that option if Java is being built) otherwise I would have not
included it.

I did "CC" him on this when I mentioned him in comment #7 but someone
removed him from the "CC". In comment #14 I left open the possibility
that someone might be paid by their Employer to fix this (or desire to
fix _their_ OS) and I don't want to steal food from their mouth.

Comment #25 (my last post) seemed valid as someone else had reported
a workaround (and not a fix), that is all that tempted me to make this
thread longer. I will refrain from further comment until either I
have a "fix" _or_ I thank one of you for fixing this (Language that I
do not use, on an OS that I do not use). I was thinking of the welfare
of others (and gcc) too much,

Rob
