Bug#337692: libx11-dev: encounter same error when trying to compile different X dependant software

[Daniel Baulig <iparanoid@gmx.de>]

Package: libx11-dev
Version: 2:1.0.0-6
Followup-For: Bug #337692

I tried to compile different software using X headers (eg wmxmms, 
wmpower and the dri radeon drivers) and encountered the same problem in 
each of the compilation steps. It's always complaining about 

/usr/include/X11/Xlib.h:3578: error: syntax error before '_X_SENTINEL'
