RFC: usage of cygwin32-/cygwin64- cross-toolchains

[Yaakov (Cygwin/X)]

Now that we're long finished bootstrapping cygwin64, I was wondering to 
what degree (if any) are the cygwin32-* and cygwin64-* packages in 
either the Cygwin distro or the Fedora Cygwin repository are of actual 
use.  If you are using any of these, please specify on which platform 
you are using them (i686/x86_64, Cygwin, F19, or if you want to move to 
F20) and to what extent (IOW "to build Cygwin package A/B/C which 
require libraries X/Y/Z").  This will help me best manage my time wrt 
keeping these updated.

TIA,

Yaakov
