For fedora it will not be possible to do a special 32bit compile on the x86_64 arch.
Wait ... no gcc -m32 on Fedora x86_64?
Hence the only way is to have the default x86_32 version and a x86_64 version to be parallel installable. While it may be possible to use a different WINEPREFIX for the x86_64 version (which would have been my short term solution) it is not desirable for the users.
Until WIne's WoW64 implementation works (which from what you said before may be never), users will have to put up with separated 64bit and 32bit Windows apps. The best solution is to use a separate WINEPREFIX.
Note that they would have the same issues if they were running Windows natively.
