I was involved in porting a project with a Unix background (Solaris,
then Cygwin and Linux, and even FreeBSD) to SUA. I was expecting SUA
to be slightly faster than Cygwin since it has its own subsystem
rather than being implemented on top of Win32. However compilation
times (for a bit over 200k lines of C++) were almost identical.
Unfortunately, our project uses poll(), which on SUA does not work
(except for /proc).

Note that SUA has a rather BSD-ish flavor (for instance, bash is not
even present in the default install); whereas Cygwin is very much like
the GNU system.
