Without looking at the specifics of the patch for now, I am wondering
what other people think of the idea itself. For myself, I can see how
a warning might be useful, but forbidding it might be viewed as
a little excessive, particularly if there is a bug in GDB (or in
the debugging info!!!) that makes it think it's constant when in fact
it's not.
