I'd say that, in general, it's better to build binaries as 32 bit
(note that this is the only way you can build them with the gcc we
have). 64 bit executables won't run on machines that have booted the 32
bit kernel (sun4m machines), so 32 bit is the least common denominator.
For example, most of the Solaris userland is still built as 32 bit
executables.
