Try compiling the program with `gcc -ansi`, and you'll see that "asm"
and "volatile" are undeclared. The motivation for my patch comes from
barrier() being declared differently in compiler-gcc.h.

However, the tree is polluted with the non-ansi versions anyway;
compilers will continue to support them for decades. So, I'd request
you to drop the patch.

Thanks.
