All shall rejoice for I have found the issue and corrected it.
The new zip file when it gets uploaded will have the issue fixed.
In order to get clang to work however you must add this to your
size_t.h file in /boot/develop/headers/posix
#ifdef __clang__
        typedef long signed int         ssize_t;
also ensure gcc4 is the one set to be used if on a hybrid.

There is probably more to do but i suspect this allows clang to be
used to compile most user programs and i shall attempt a few from the
haiku trunk once i get the hang of jam...
