You also need to manually populate /usr/include32 since it doesn't exist by default and may still get bitten by stuff in /usr/local/include. Do you have a script (or installworld patches) to do this? amd64/112215 includes a first attempt at updating the gcc specs (though it's missing the include handling), as well as some of the remaining problems. >Ideally x86_64 platforms run *all* i386 programs (that don't >depend on a 32 bit kernel). Agreed. -- Peter Jeremy Please excuse any delays as the result of my ISP's inability to implement an MTA that is either RFC2821-compliant or matches their claimed behaviour.
