bmoeller>
bmoeller> (void (*)()) (long) cb
This may very well be a problem on architectures where a pointer is 64
bits while a long is 32 bits. I think that some versions of Compaq C
on Alpha (VMS and True64) have this quirk...

bmoeller> function that gets this pointer as an argument has to
bmoeller> retrieve the actual function pointer from inside this data
bmoeller> object, i.e. use *((void (**)()) arg) where arg is the void
bmoeller> * argument passed to it.
I was pondering such a solution, but I foresaw a problem with it:
&strcmp is the same as strcmp, and that might be a difficult bug to
find...
