Charles sent me some changes that I will be incorporating and testing.
They seem to have the same design goals as my changes.
BTW: There is a line in the patch that is messed up. It is something
... &= ~(MCDSOMETHING & MCDOTHER & MCDTHIS & MCDTHAT);
All of the ' & ' should be ' | '. Sorry about the confusion. It does
explain why I couldn't get the TOCHDR to re-read ;-).
Let me know if any of you have any problems with the changes. Like I
said, Charles will be sending out a new mcd.c in the future, so these
changes are not permanent, to say the least.
