Compiler warnings on Debian Sid kfreebsd-i386

[Ken Sharp]

Following my previous e-mail 
(http://www.winehq.org/pipermail/wine-devel/2013-August/100754.html) I 
have since moved from Wheezy to Sid to work around a Debian bug.

libxml2 has been updated (2.8.0+dfsg1-7+nmu1 --> 2.9.1+dfsg1-3) as a 
result and introduced some new compiler warnings:

/home/ken/wine-git/dlls/msxml3/node.c: In function ‘htmldtd_dumpcontent’:

Hopefully these mean something to someone.
