Thanks for the explanation. This prompted me to check the compiler
options and there is a '-xthread' option for controlling local thread
storage; it has an optional string following it to control whether one
is compiling PIC or not.

Unfortunately compiling with -xthread (defaults to -xthread=dynamic),
produced no change in the clip-test program---still complains about
'No composite function found'.



Also, it isn't possible to set the above macro to zero as this
is used as the length of an array  in the cache_t type and the
compiler complains about a zero subscript.
