In fact, the patch got reviewed and was rejected:

http://gcc.gnu.org/ml/gcc-patches/2004-12/msg00889.html

i think, this decision remains to be discussed since:

http://gcc.gnu.org/ml/gcc-patches/2005-01/msg01423.html :

"A rewrite of the type representation (to bring it closer in line with 
C++/Java) is planned, but in the gcc-4.1 time frame at the earliest."

what would mean that for about one year (until 4.1 is out) GCC will 
ship with a broken ObjC compiler. This is IMHO not acceptable for 
GNUstep, given the fact that Zem thinks, there is currently no other 
solution possible:

http://gcc.gnu.org/ml/gcc-patches/2005-01/msg01516.html

I will ping the reviewer to ask him if he couldn't approve the patch as 
a timed solution, marked with a "FIXME" comment. See my next mail.


You can help this cause too if you express your opinion on that at 
address@hidden . Discussing that subject here doesn't help the cause a 
lot, really.
