The e-mail address given in the first paragraph of the PGCC Support
Web page (http://www.gcc.ml.org/questions.html) is apparently inaccurate.
"pgc AT goof DOT com"
Alas, the bad address is also the address to be used in reporting errors in
the PGCC Web page. (Kinda recursive.) That's why I'm posting this message
to the list rather than reporting it in private e-mail.
FYI.

Subject: Optimization greater than -O2 when compiling compiler?
Back when v1.1.0 of egcs/pgcc was released, I asked one of you guys, Marc
or Jeff, about the advisability of building the egcs/pgcc compiler with an
optimization level greater than -O2. I was strongly advised against it.
Now that it's 2 releases later, and considering all the bugs that have been
fixed since the v1.1.0 release, I'll ask the same question.
How risky is it to build the egcs/pgcc compiler(s) with an optimization
greater than -O2? If cranking up the optimization is still a bad idea for
the compiler executables, then how about just increasing it for the
libraries?
I spend a *lot* of time running pgcc and would like it to run as fast as
possible, but not if it means increasing the chances of it generating bad
code.
Thank you.
