Right.  Basically when gcc-2.7.2 has generated incorrect code they've tweaked
the asms to work around the problem.  Over time they end up with a set of
asms that generally works with gcc-2.7.2.

However, that does not mean they will consistently work over time -- as the
source around the asm changes, the register allocation and reloading needs
will also change, which may again trigger problems.
