:don't think there's any way to get rid of the warning without changing
:the declarations.

:In my opinion, the use of "-Wcast-qual" is bogus. Often the whole
:point of a cast is to remove a qualifier such as const. It's one
:thing to warn when that's done implicitly, and quite another thing to
:warn when the programmer has clearly expressed his intent through the
:use of a cast.

There are only a few cases where cast-qual is bogus. 99% of the warnings
it generated were quite real. Maybe not bugs, but definitely programming
by misadventure. Volatile and const are only going to become more
important as we get deeper into the SMP issues. Especially volatile.
cast-qual is necessary to keep people from making bozo mistakes.
