Under Solaris2.8 the current lang/gcc3 package makes a gcc that can only
produce 32bit binaries. This means I can't make a functional lsof:
#gcc -v
Reading specs from /usr/pkg/gcc3/lib/gcc-lib/sparc-sun-solaris2/3.3.4/specs
Configured with: ./configure --prefix=/usr/pkg/gcc3 --host=sparc-sun-solaris2 --enable-shared --enable-languages=c
Thread model: posix
gcc version 3.3.4
#gcc -m64 it.c
cc1: error: -m64 is not supported by this configuration
#lsof /
lsof: FATAL: lsof was compiled for a 32 bit kernel,
but this machine has booted a 64 bit kernel.
If I comment out one line in gcc3/Makefile.common I can build a gcc that
accepts both the -m64 and the -m32 flags, and lsof compiles and runs fine:
#cvs diff -c1 Makefile.common

Unfortunately, this new gcc isn't able to compile gcc3-c++, as it loops
forever. It looks like it's stuck in the "bmake configure" stage, but if I run
that by hand it works fine. It's not until the final "bmake" that it starts
looping:

I'm guessing it's because something is still set to "solaris2" instead of
"solaris2.8". Can someone more familiar with gcc and pkgsrc take this on and
come up with a good solution?
