I did not have time to make much tests, but yes it is faster.
I compared cygwin64 with mingw32.
factor(2^256+1) is about twice faster.
make test-rnfkummer is only 20% faster.

I would certainly be interested by time comparaison between 
cygwin64/cygwin32 and cygwin32/mingw32.

Also I would be interested to know whether Configure --mt=thread
works on cygwin and what are the performances.
