[PATCH 00/04 libdrm] The rocky road to building with -Wextra

[Emil Velikov]

Hi all,

A few small patches, that handle the initial step of building the whole 
of libdrm with WARN_CFLAGS (-Wall -Wextra and friends).

The first patch makes sure we build everything at make distcheck time, 
followed by a couple of warnings-turned-errors, and finally adding the 
cflags everywhere in the project.

Individual fixes for the 66 warnings will follow up in due time :-)

Thanks
Emil
