warning: `x' might be used uninitialised in this function

[Giuliano Procida]

I get the message of the subject. Needless to say, I don't have a
variable `x'. However, "x" is the name of an argument to an inline
function that calls another inline function (argument also called
"x") that is pure assembler (return byte-swapped 16-bit word).

This is egcs-2.91.63, the bug was not listed in the info file. I
can trim out the offending code (-E output) and post it, or some
or other of the dumps; let me know.

Thanks,
Giuliano Procida.
