Details:
I upgrades OpenSuse to 12.1 which comes with gcc 4.6.2 and now configures
fails to detect Objective-C support with the following error in config.log:
configure:12635: checking whether objc really works

configure:12669: $? = 1
configure: program exited with status 1
The first thing I notices was that the link to objc was wrong on the system:
ls -l /usr/include/objc
lrwxrwxrwx 1 root root 49 14. Feb 2011 /usr/include/objc ->
/usr/lib64/gcc/x86_64-suse-linux/4.5/include/objc
But changing this to the new objc directory didn't help. To me the problem now
seems to be that the compiler picks up the runtime.h file from the previous
configuration with gcc 4.5 which points to the ObjectiveC2/runtime.h instead
of using the one that comes with the compiler (or rather libobjc). I think we
should not include any of the GNUstep Header installation directories here.
This may either be a GNUstep make error or a base error, not sure which.
Removing the file /usr/GNUstep/System/Library/Headers/ObjectiveC2/runtime.h
solves the problem.
As an add-on, I see this warning a lot in the config.log file with gcc 4.6.
Perhaps we need to change the check for an old runtime?
