I meant an "extra" bump from 4.5 -> 4.6 and 4.6 -> 5.0.  The bump
for 5.0 is assumed, since people are doing evil things to system

I saw a posting of some of the breakage.  There was a type that
wasn't defined in scope in a prototype, and then there were a
couple that were missing (e.g. "unexpected ;") because of some
bogus includes.  I didn't really see anything that I could blame
on GCC31 itself (I admit it has problems, just not those problems).

Not really.  The headers that get affected by this are RTTI, and
a couple of others.  They would let you compile, and then core dump.

One of the complaints (not sure if it was yours... Trish posted that
the GDB worked locally [albiet an older build]) was "compiled OK,
but core dumped".

I needed RTTI on a 3.x system for "typeof" for exception identification
of an exception class derived from a base exception class, in order to
implement Java 1.1 APIs in C++.  Basically, going from GCC 2.93 to 2.95
ended up getting the wrong header files because the .mk file overrode
the ports installed compiler header files (and library) when the DESTDIR
was set.

So if you are having this problem (ports pretty uniformly sets it), it
could just be that the system compiler and the ports version header
files don't interoperate.

You can ask Julian, Archie, or Mark Peek about this; we had to build a
new builkd environment to include the GCC 2.95 port, and I had to hack
the heck out of the makefiles to put the port header files ahead of the
system ones, when using the ports compiler.

You could probably do this (mostly -- only for one port) by "which"'ing
the $(CC), and then overriding the path by jamming -I and -L into the
LDFLAGS and CXXFLAGS conditionally: my hack did it unconditionally).

The real issues is narrowing down "broke" a bit, I think, to see if
this could be the problem.  8-).

Gotta tell you though: using GCC31 from ports on -stable *should fail*
when building other ports, because of this, so if it doesn't, it may
be that the *new* header files are broke, relative to e.g. libgcc2.a.
