Ah, you are right.  I modified the conftest.c compile command so that it has 
-L/usr/lib as the first -L argument, and it now compiles fine (my libobjc from 
libobjc2 lives in /usr/lib, whereas the gcc versions are in 
/usr/lib/gcc/ARCH/VERSION/...).

I didn't realize it was necessary to force-uninstall the gcc libobjc.  This may 
not be possible for me, because I'm compiling in a build system where I do not 
have root access.  Is there a way to tell my gnustep clang compilations to use 
/usr/lib for libobjc?  I could try modifying the configure scripts to add 
-L/usr/lib first on every command line's list of link directories, but I'm a 
bit worried that that might interfere with something else.  I will keep 
looking, but please let me know if there's a canonical way to do it.

Thank you,

David
