[Wine] Ubuntu 10.10 AMD64 and building wine

[A Nonny Moose]

Hooray!  I got a new machine.

However, if I want to continue doing things with wine, I need a little more information than is in the wiki on building wine for 32-bit and/or 64-bit operations.

First question:  Are the instructions for 10.04 still OK?  Is there any real change?

Second question:  If I follow the line in the RegressionTesting page that says:
[code]CC="ccache gcc -m32" ./configure --verbose[/code]
will it be OK to build the 32-bit version?

Third question:  With a 64-bit machine running the 64-bit O/S should I worry about running a 32-bit version at all?
