okay - here is another question:
which flle do i edit do add words for coloring? *e.g. i typedef long int to UINT32 and i want UINT32 to have the same color as a varible.
In your .vimrc:
syn MyWords UINT32 LJR pbharris vim
hi MyWords ctermfg=blue
Here's what it does. MyWords is a variable which conatins the words UINT32 LJR pbharris and vim. On the second line, we say, highlight MyWords with the color blue. You can change blue for something else.
