	Using xlc++ / xlC and adding the GCC support libraries probably
will work.  Or are you asking about compiling everything with the XL
compilers?

	Will GCC use a "C" wrapper to interface with PPL or explicitly
invoke the C++ interface?

	If everything is self-contained, it should work, but C++ mangling,
exception handling and constructors/destructors will not interoperate, for
instance.
