The following source file compiles OK and generates working code using
GCC 1.35 without -O.  GCC 1.35.95 without -O complains about
"inconsistent operand constraints in an `asm'", and _both_ versions
die from signal 11 when compiling with -O.

Configuration: GCC 1.35 on a Sun 3/50 running SunOS 4.0; GCC 1.35.95
on a Sun 4 running SunOS 4.0.
