-Building 64-bit binaries is very similar, but you'll need to replace "i686" with
-"x86_64" everywhere in the above instructions. Note that you can build both
-32-bit and 64-bit binaries from the same Cygwin installation, provided that you
-install both the mingw64-i686-* and mingw64-x86_64-* packages; and you can run
-the Cygwin setup program to install more packages at any time.
