Hi,

I actually switched to gcc 4 and that cleared a lot of things. I
still havent gotten nsalert to work, but with many things turned off,
the application does compile now.
I tried making my nib files gmodels then .gorms.  While that did
work, it also really messed things up. The Gorm file is so corrupted
that once i save it, i cant open it anymore. There are a few minor
things, but beyond that i think OSXnews will have Gnustep  sibling
very soon, possibly this weekend. I am releasing 2.08 today and will
use that code base to make the first gnustep build. I will probably
post back on the NG with details and links

Thanks,
-Anu
