Ah yes, this may be a problem.  Though with pooma I never used exception
handling, and with gcc you can turn it off completely with 
-fno-exceptions.  That may improve the situation on Windows a bit.

I guess most useful would be _updated_ project files for the 2.4.1 
release.  I put the ones from the old CodeSourcery repository at

http://www.tat.physik.uni-tuebingen.de/~rguenth/pooma/pooma-2.4.0-ide.tar.gz

they are probably in the state of 2.4.0, but I don't know.  Maybe 
someone with access to Windows/MSVC can check what they do with the
FreePOOMA 2.4.1 release and provide a tarball of updated files?  I'd 
stick them to the FreePOOMA download area then.  If that guy can also 
write one or two sentences for the casual windows user, that would be great.

Thanks in advance,
Richard.
