32-bit Cygwin has just been demoted to a third-class citizen. Cygwin 3.3.0 was
released this morning, with a deprecation notice that it is the last major
version supporting 32-bit installations. In view of this, I don't want to put
any energy into supporting native compilation on 32-bit Cygwin, and I doubt if
Achim does either.
