Wow, now it gets interesting - I think I could even hear my SPARCstations in storage making a few jumps! :-D I thought support was removed somewhere in 3.x.

Running ILP32 software on a 64-bit CPU sure seems unpopular these days... (but it's still half the memory and bandwidth nonwithstanding the beating x32 took not too long ago).

I just added it for completeness sake. If the 32-bit support is kept working in source, it will be possible to build packages locally, for example. Adrian -- .''`.

I agree with a "bit less" memory. A "bit less" bandwidth? Maybe. However the overhead in a code base isn't worth the effort. Dennis
