Heh, well, IMHO, the GOTO's are evil and should be shot, killed, mangled,
etc. Following this theory, managed to rework the offending section of
code to not need a goto. (althoug it then required about 3 move levels of
'if then else' blocks)

I posted the patch to the list earlier, let me know if you want it.
