To get Octave to build under mingw32, one would have to emulate the
subprocess management and signals, both of which are hard to do without
resorting to Win32 API (the C runtime is strictly ANSI with just a few 
POSIX routines thrown in for good measure).

I went through this when I ported our simulation software, and ended
up using Mingw32 for the computational part and cygwin32 for the
simulation management module which I didn't feel like rewriting.
Essentially I have the same code except for a few emulation routines
that runs on Unix and Win32.

The reason I went with Mingw32 is strictly performance -- in some cases 
10-15x speedups for some of the CPU and/or I/O intensive numerical codes.
I still have nightmares however trying to get around bugs in some of 
Microsoft C runtime routines (CRTDLL and MSVCRT).
