gcc with Objective-C support

[Andreas Höschler]

Hi all,

Sun has released a tweaked version of gcc 4.2.0 with some optimizations  
for the SPARC platform.

Here are the links:

My attempt to build the sources with Objective-C support failed:

Unfortunately Sun has not cared much for Objective-C support so far.  
Can this simply be added to the code tree from Sun. I would like to  
test whether the mentioned optimizations have a positive effect on  
GNUstep applications running on Solaris SPARC.

Hints are greatly appreciated!

Thanks,

  Andreas
