Not again.

Please people, come join us in the 21st century. 64bit has been around
long enough. If there is still an app that fails to compile/run on
64bits, its worthy of dropping it entirely.

If something basic like perl would still make problems on 64bits, there
would be a legion of programmers fixing it.

There is no problem running any contemporary app on any contemporary
distribution on a 64bit processor and system. These apps also don't
take up more memory, they get a very little bit bigger because
memory-addresses are now 64bits instead of 32bits. But they should be
using position-independant-code anyways. And now an app can also use
more then 3Gbyte of ram. And your system can also have more than 3.2GB
of ram without ugly clutches like PAE.

Nowadays 64bit isn't an exotic exception. I had trouble last week
installing a box: Took me one attempt to realized that my hw-people
gave me a 32-bit-only machine!

Have fun,

Arnold
