Duncan,
   Yes, I was trying to use dragon-egg svn with llvm release-2.7 branch (because
I was in the process of preparing llvm/llvm-gcc42 2.7 fink packages and had
those handy). I'll try again with llvm svn. FYI, I have posted the --enable-plugin
fix patch for darwin to the gcc-patches mailing list...

http://gcc.gnu.org/ml/gcc-patches/2010-04/msg00516.html

I think we need one more darwin-specific FSF gcc patch for dragon-egg
(as gcc 4.5.0 doesn't installed the required darwin-sections.def into
/sw/lib/gcc4.5/lib/gcc/x86_64-apple-darwin10.3.0/4.5.0/plugin/include/config).
I am still pondering how to properly do that in the Makefiles.
  Have any prior dragon-egg gcc patches been committed and do you intend
to post the i386_static.diff to gcc-patches?
              Jack
ps I did notice the dragon-egg web page said that exception handling was
broken but I did see some recent commits on that feature. What is the
status of exception handling in current svn?
