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. Cheers, Bill.
