Hey, no one said this behavior was consistent :-)

It's a situation where the two "platforms" are not all that different---
the system can run binaries from both---and avoiding the need to
rigorously cross-compile from one to the other is a big convenience.

Obviously, Cygwin vs. MinGW programs is a different comparison from 32-
bit vs. 64-bit programs, but it's close enough to allow the same
argument to be made.
