1) No, you didn't install a 64-bit version of Cygwin.  "uname -a" should
make that clear.  You'll need to instal a 64-bit version if that's what
you want.

2) Cygwin doesn't build Linux apps.  If you have a cross-compiler then
it won't automatically decide to build 64-bit Linux apps because you
are on a 64-bit sytem.
