If anybody is interested, I have updated the vim (gvim) syntax
file for version 0.75 of the D spec. It is located at

http://www.vim.org/scripts/script.php?script_id=379

I have done some basic testing, but since I don't code in D
very often I'm not likely to find errors in a timely
manner. If anyone finds any problems or have suggestions,
please email me.
