A friend has pointed out that although the ANSI C draft does indeed
outlaw casts between function pointers and data pointers, it lists
such casts in the "common extensions" appendix.  It's hard to do things
like debuggers and on-the-fly code generation without such casts.  But
use of casts, instead of unions, for more mundane requirements remains
a poor idea.
