Not this thread again... I kept this reply around just in case someone
asked this again.

THIS FIXES THE TCSH NO JOB CONTROL BUG!!!!!!
If your kernel sources predate this commit then the current tcsh packages
on freebsd.cdrom.com will give you the no job control error.
IF AND ONLY IF, your kernel predates this update, will the following patch
to the tcsh sources temporarily patch the problem. The real fix,
is to install a newer kernel.
NOTE, all that I did was change all occurances of NTTYDISC to TTYDISC
