umm, ahh, rechecking again now.

Its no worse than the function signature casting that is 
already being done.  The second argument is not clobbered
for the caller, because the callee linkage saves all clobbered 
registers, and the callee couldn't care less, because it
saves and restores all registers that it clobbers.  It's
perfectly safe; I've read the assembly umpteen times over 
the years.  Take a look at GTK signals, where this is done
all over the place; the added extra argument is usually 
a gpointer to 'user-data'.

I uhh, guess I needed to check some other things in too ....
