"Do nothing" meaning what, exactly?  That you don't see any more
colors, only their names?

Anyway, if Co was incorrect, it probably means the comands to produce
the extra colors (beyond the normal 16) are also wrong.

I'd suggest to check the way you built and installed your xterm.  It's
been a long time since I tried that myself, but IIRC, if you go by the
README, you get a 256-color capable xterm with no reason to fiddle
with termcap entries.

Failing that, perhaps Tom (CC'ed) could help us?

All you need is what's on lisp/term/xterm.el in the CVS codebase.
