[parisc-linux] input constraints in atomic.h too loose ?

[Mike Frysinger]

while building glibc-2.5/cvs with gcc-4.1.1, i hit an error about invalid 
operands in the locking code ... looks like the declared constraints for the 
inputs in atomic.h are too loose ?

$ hppa2.0-unknown-linux-gnu-gcc -O1 -fPIC vfprintf.i -c
