Subject: How to (almost) build a 64bit lang/gcc3 on Solaris2.8

 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
   Index: Makefile.common
   RCS file: /cvsroot/pkgsrc/lang/gcc3/Makefile.common,v
   retrieving revision 1.8
   diff -c -c -1 -r1.8 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

  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?
