32-bit cvs wine on x86_64

[Ivan Gyurdiev]

I'd like to compile 32-bit cvs wine, on x86_64 [ since 64-bit wine can't 
run 32-bit apps, and cvs wine has many fixes over the released wine that 
I'm interested in ].

Are there any undesirable side effects of enabling the 32-bit repository 
on x86_64?
If not, why isn't this done by default (instead 32-bit packages are 
being added to the x86_64 repo)?

If yes, why doesn't Fedora ship:
- 32-bit wine in x86_64 (along with 32-bit libraries it requires)
- (-devel) packages for 32-bit libraries available in the x86_64 repo. 
In general, what's the target audience and purpose of the (-devel) 
package, and what determines when one is included, and when it isn't?
