	Gabriel's patch is the correct way to address the problem and
should be the one which goes into the public sources.

	I do not understand, however, why the patch only includes the "=m"
constraint on regw() and not regw16().  All of the inlined functions
should have constraints which reference the actual memory address read or
written to ensure proper dependencies in optimized code.

	The problem was the unnecessary "volatile" not the memory
constraint.
