Building RTEMS for a host?

In general, Win2000/XP as a host is supported through either the cygwin
tools or the MinGW toolset, see:
http://www.rtems.com/wiki/index.php/MinGW_Tools_for_Windows

I have no experience, whether you can run a RTEMS executable under
Windows/cygwin. Since the cygwin environment is not a perfect emulation
of a posix environment, I would expect some problems there. Maybe some
other guy has experience here?

In general, I would prefer a linux system as a host (and a base for
simulation).

wkr,

Thomas Doerfler.

But AFAIK this method is no longer so heavily used due to the benefits you get from the simulator approach.

In the documentation of RTEMS I always read about building RTEMS for a specific target. Is there a way to use RTEMS on a host, because the first testing activities for an application a more effective on a host?
