Neither torque or maui default to either 32bit or 64bit builds.  They just get
built by your compiler.  Your compiler has a default arch.  If you are building
both packages with the same flags, then they should have the same arch.

The following should build to the desired arch:
./configure CC="gcc -m32"
./configure CC="gcc -m64"

The torque tarball has some notes in the 'INSTALL' file.  Also, for 64bit
machines, consider build torque for both arches and install both client/devel
packages for compatibility.

For Maui, you *must* set -D__M64 when building 64bit.
