Hmm. That's odd. Everything was compiled with clang and clang++ and linked with
gcc
I followed these directions:

I also uses -fblocks everywhere in my own makefiles. I'll double check just in
case.

Ok. I'll do that and recompile. That's probably the reason (my own makefile use
-fblocks but the GNUstep ones might not).

Good point. My own sources are compiled as follows:
clang -g -I/usr/GNUstep/System/Library/Headers -I. -fblocks
-fobjc-nonfragile-abi -c CPFactory.m
so I already use nonfragile and blocks. But I didn't muck with the GNUstep
CFLAGS and I bet that these guys do not have these two options.
The code runs though. Kudos on the GNUstep libs. Once I figured out (with the
list help) the magical makefile, it all compiled cleanly (only this runtime
issue left).
Thanks David!
