[xml] xmllint problems

[oliverst online de]

When I run xmllint with "--valid" or "--postvalid" it does crash when using the XML output of MAME as input 
(http://www.breaken.de/temp/output.xml).

I am also having a problem to properly parse it. I don't get the "mame" node as root node, but a node below 
it and the "mame" node has no children at all. Guess it is because of the DTD, because when I remove it, it 
does work. I have absolutely no experience with DTDs, so maybe you can point out the problem.

xmllint also says, that "--c14n" and "--exc-c14n" is an "Unknown option". IMO it should say, that c14n is not 
compiled in. This should also be the case for the other options, that are compile flag dependent.

I am using libxml2-2.6.22 buld with MinGW.
