[Qemu-devel] [PATCH 0/1] major / minor macros are to be included from <sys/sysmacros.h>

[Andreas Grapentin <andreas@grapentin.org>]

Building qemu fails with glibc-2.25 and gcc-6.3.1:

> qemu/qga/commands-posix.c:656:13: error: In the GNU C Library, "major" is defined
>  by <sys/sysmacros.h>. For historical compatibility, it is
>  currently defined by <sys/types.h> as well, but we plan to
>  remove this soon. To use "major", include <sys/sysmacros.h>
>  directly. If you did not intend to use a system-defined macro
>  "major", you should undefine it after including <sys/types.h>. [-Werror]
>          *devmajor = major(st.st_rdev);
>              ^~~~~~~~~~~~~~~~~~~~~~~~~~

A trivial fix is to #include <sys/sysmacros.h> in the respective files.
