[Qemu-devel] [PATCH for 2.6] configure: Allow builds -Weverything

[Stefan Weil]

The clang compiler supports a useful compiler option -Weverything.

As this option triggers warnings in glib header files, too, testing
glib with -Werror will always fail. A size mismatch is also detected
without -Werror, so simply remove it.

With this patch, it is possible to build QEMU using this configuration:

./configure' --cc=clang-3.7 --cxx=clang++-3.7 --extra-cflags="-Weverything 
-DHAVE_FSXATTR" --disable-werror

(HAVE_FSXATTR avoids a fatal build error because of structure redefinition)
