This pio.h example is very close to the VAX movc3 example given at the bottom
of page 179 in the GCC 2.8 edition of "Using and Porting GNU CC" by Stallman.
The legality of clobbers overlapping with input operands is mentioned at the
end of the discussion of 'clobber' on page 293.

Either this responder does not understand the full definition of clobbers,
or egcs is providing a different syntax to express an input that is also
clobbered, or egcs has broken this feature relative to GCC 2.8.
