You can do this already, though not with a compiler option.  It would be
possible to do it with a compiler option, but it would be tricky to
implement - basically the compiler would have to generate a small C
file, compile it, and link it into the excecutable, and somehow avoid
conflicting with any other hooks that the programmer had already
defined.

So, I'm enclined not to do this on the grounds that the payoff to effort
ratio is small.  But, as usual, if there's strong demand then we'll
probably do it anyway.
