It does seem a bit anomalous that the last one doesn't work, as most
of the other wincmd accept a prefixed count to specify the window on
which it should act (or the number of windows to traverse).

So you'd have to do a combination of "go there, then close":

:exe winnr . "wincmd w" | wincmd c

This does have the potential to leave you in different window, so you
might want to preserve your current window, jump to the one you want
to close, close it, then jump back to the original. Something like
this (untested) mess:

:let g:oldwinnr=winnr() | exe winnr . "wincmd w" | wincmd c |
exe g:oldwinnr . "wincmd w" | unlet g:oldwinnr

Ugly, but functional.
