make.vim fails to recognize valid makeIdent with dashes during assignment

[cub]

1. Create a Makefile with a variable that has dashes:
foo-bar=baz
$(foo-bar):

2. Observe that syntax highlighting fails for assignment, but $(foo-bar) is highlighted correctly.
3. Apply the attached patch; restart vim; observe that the bug is fixed (root cause: the \w pattern excludes dashes).

The bug definitely exists in 10.04 and 11.10. I'm guessing it's universal. If you need exact packages:

2:7.2.330-1ubuntu3 (ubuntu 10.04, amd64)
2:7.3.154+hg~74503f6ee649-2ubuntu3 (ubuntu 11.10, i386)

Well, the GNU make manual says "variable names containing characters other than letters, numbers, and underscores should be avoided, as they may be given special meanings in the future, and with some shells they cannot be passed through the environment to a sub-make".

Also, you should contact the script maintainer about this. In the meantime, you can add those new syn-match lines to ~/.vim/after/syntax/make.vim to take advantage of them without modifying the system-wide syntax/make.vim.
