	Bob Rose (naucse!rrr) came up with this awhile back and offered a fix
for it, I implemented the fix and sent it off to GNU, and It appears to be 
fixed in v1.26. I haven't compiled it, so I'm not sure if it works, but its
supposed to :-).

	The fixes look alot like the ones poested here, and I will mail out the
new tm-3b1.h file if anyone is interested. Thanks Tom for finding and fixing 
the problem.
