Correct, mxe is a cross-building environment, but it builds Octave for
Windows using the MinGW runtime and compilers, not Cygwin, they are
different projects with different approaches.

Building the installer is documented and should be trivial for anyone
with enough time and CPU cycles to do it, see
http://wiki.octave.org/Windows_Installer.

As a package maintainer, the salient point is that native Windows and
Cygwin have some similarities but are different operating environments
that need to be tested individually. There are preprocessor macros and
the ispc/isunix functions to differentiate them if needed.
