I don't really mind either way. I first raised the question of whether 
JonY's package would support -m32  or just -m64. His answer was -m64 
only, but then he almost immediately released a revision #2 that was 

I assumed that would be the "only" version, but in the NEXT email 
exchange, he stated he was "saving" the /i686-w64-mingw32/ directory 
tree for the (multilib?) version that would default to -m32.

Now, maybe his original plan was to propose two separate non-multilib 
compilers, and he didn't think through the implications TO that plan 
that switching to multilib would cause.

But again, I don't care either way: one multilib with a specific 
default: fine.

Two non-multilibs, one for w64 and one for w32: fine.

Two multilibs, basically identical except for the different default (and 
the duplicated /{x85_85|i686}-w64-mingw32/ installation trees): also fine.

THAT's up to JonY.  He seems to have settled on the third of these 
options (especially given how the pthread stuff was packaged), but the 
other choices would also be A-OK IMO.

Whatever's necessary to build both 64bit and 32bit binaries using your 
stuff.  What that actually means in terms of configure options...is 
JonY's decision.  I'm just trying to help him package what he wants to 
provide, in a way that will let setup.exe be happy, and not violate (too 
many) cygwin packaging standards.

I'm really not trying to pile extra work on JonY.
