Unfortunately, I should have double checked that the following
fix (authored by Dave Goehrig <dave@cthulhu-burger.org>, not me),
was really in the CVS... it's not, as of stable 1.2.3 at least.
Please include it, it fixes a segfault on exiting a program which
disabled MOD music during its execution.
