So I have installed last versions of GNUstep installers on windows and
compiled clang.
I have also checkouted libobjc2 and I entered:

CC=clang make

Making all in toydispatch...
Making all for library toydispatch...
 Compiling file toydispatch.c ...
 Linking library toydispatch ...
Creating library file: ./obj/libtoydispatch.dll.a
Making all for library libobjc...
 Compiling file class.c ...
cc1.exe: warnings being treated as errors
class.c:125: error: '_objc_lookup_class' redeclared without dllimport
 previous dllimport ignored
make[2]: *** [obj/class.c.o] Error 1
make[1]: *** [internal-library-all_] Error 2
make: *** [libobjc.all.library.variables] Error 2

$ grep -Ri "objc_lookup_class" * (By the way grep inside your installer 
grep is buggy because it's only a few kB while standard 
one is at least 1MB, so I have replaced
grep.exe, fgrep.exe and egrep.exe by last version from mingw 
see grep-2.5.4-1-msys-1.0.11-bin.tar.lzma).

objc/objc-api.h:** This is a hook which is called by objc_lookup_class and
objc/objc-api.h:objc_EXPORT Class (*_objc_lookup_class)(const char *name);
objc/objc-api.h:Class objc_lookup_class(const char *name) OBJC_DEPRECATED;

I tried to add the same export declaration but stil got errors.

Any idea ?
