In message <20030702000902.GA15274@NetBSD.ORG>, you write:

Hmm, interesting.  I've by no means kept up with gcc 3.x recently, so 
this is good to know.

Heh, the funny thing is that rebuilding the gcc3 package with the 
previously built pkgsrc gcc3 doesn't seem to work, which I found out
while trying to fix the PIC-ness of libgcc :-).  I've re-added tech-pkg@
to the CC in case they care about this failure case...
