Hello,

> Is there someone working on a cygwin cross-compile for NetBSD?

I have a whole page on my website devoted to this, including a patch 
that you will need to apply to make it work. I must admit, I haven't 
checked it in about 10 days (and there have been a number of checkins 
that could, potentially, have caused some problems), but please try it 
and let me know of any problems you encounter.

You can read about it, and download the current version of the patch at:

> Where can one read up on the state of native multithreading in NetBSD?

There have been a number of discussions about this in the various 
mailing lists, including this one.

> What version of GCC will support xscale or powerpc NetBSD ABI?

The version that is currently in the source is 2.95.3. I haven't tried 
the XScale variant of that, but I am using the PowerPC variant quite 
extensively.

HTH,
