The WINCE implementation might be helpful here.  It depends on some data 
tables taken from ICU which we decided not to check in, but you can 
still find them in the older patches attached to this bug:

I don't think this is worth the pain, since it's entirely a build-time 
dependency and won't affect your generated library at all.  Is 
installing cygwin really that hard?  (If it's a matter of bloat, can you 
replace the cygwin tools with msys?  I haven't tried.)
