There are cygwin 64- and 32-bit native compilers and mingw 32- and
64-bit compilers on the setup.exe menu in case you mean to build for one
of those targets.

I have a 64-bit Windows laptop, and installed Cygwin several years ago.
I wish to verify that I did install the 64-bit installation.
I get the following results:
cygcheck (cygwin) 1.7.15
If I did install the 64-bit version, when I rebuild my Linux app on
Cygwin, do I automatically get a 64-bit executable (that will not run
on a 32-bit Windows computer)?
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
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.
