That was a contributed patch; I did wonder about it, but as it worked
for me (on Linux), I left it alone.

Not quite, since a typedef is not a #define. I suspect that we probably
have to do the typedef int BOOL unconditionally (as it used to be) and
whoever's system gives a compiler warning will just have to live with
it.
