Cygwin is a Unix environment for MS-Windows, implementing all the Gnu
tools. See http://sources.redhat.com/cygwin. It works quite well, but
ACT decided to use a different approach to implement GNAT on Windows.

Yes, GNAT can be built as a cross-compiler. That is the only way to
put it on a platform for which you do not have a binary. However, you
must know what you are doing, and the build instructions that come
with the source are not particularly helpful; it can take some
experimentation. This situation may improve when GNAT is released on
gcc 3.1.
