The "matchit" plugin for vim is supposed to allow you to use the % key to jump between matching start/end tags when editing HTML, as well as /* and */ comment delimiters when editing other kinds of code.
I've followed the exact instructions in ":help matchit", but % still doesn't work for me.
It seems silly to ask "Why doesn't this work?" so instead I'm asking How can I diagnose the problem? Pointers to references are welcome, but specific vim-plugin-debugging techniques are preferred.
Here is the ~/.vim directory:

I am running vim 7.2 under Cygwin (installed Fall 2008). cygcheck shows:

In vim, :set shows:
--- Options ---
autoindent fileformat=dos shiftwidth=3
background=dark filetype=html syntax=html
cedit=^F scroll=24 tabstop=3
expandtab shelltemp textmode
viminfo='20,<50,s10,h
Notably, the syntax and filetype are both recognized as HTML. (The syntax colouring is just fine.)
If additional info is needed, please comment.
UPDATE:
Per answer by too much php:
After trying vim -V1, I had changed my .vimrc to include a line
set nocp
so the compatible option is not on.
:let loadad_matchit
loaded_matchit #1
:set runtimepath?
runtimepath=~/.vim,/usr/share/vim/vimfiles,/usr/share/vim/vim72,/usr/share/vim/vimfiles/after,~/.vim/after
(~ is /cygdrive/y)

:echo b:match_words
E121: Undefined variable: b:match_words
E15: Invalid expression: b:match_words
Hm, this looks highly relevant. I'm now looking through :help matchit-debug to find out how to fix b:match_words.
