warning list
http://msdn.microsoft.com/en-us/library/ms228296.aspx

use the number at the end (after the zeros) as the warning number


Edit by SJ at MSFT: Also, I added a note to this topic in VS 2010 steering you to the Output window to find the warning number.
Misspelling
"A comma-separted..." should read "A comma-separated..."


Edit by SJ at MSFT: This appears to have been corrected in VS2008. But please keep reporting if you see an error.
Request for reference to list of warnings

A reference to a list of warnings and their numbers would be handy here.
