Ooops. I was misled by a comment to 
http://stackoverflow.com/questions/3776098/cygwin-how-to-actually-use-gcc-mingw
this question on Stackoverflow . As it happened I had a very old version of
mingw32-gcc installed and in my PATH. Sorry about that!

"i686-w64-mingw32-gcc" (which it is in my cygwin) works perfectly. Thanks!
