New submission from Christian Heimes:
On Fedora 26, GCC is emitting warnings because we are using minor(), major()
and makedev()
from sys/types.h. The macros should be included from sys/sysmacros.h instead:
./Modules/posixmodule.c: In function ‘os_major_impl’:
./Modules/posixmodule.c:8758:13: warning: 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>.
return major(device);
^~~~~~~~~~~~~
./Modules/posixmodule.c: In function ‘os_minor_impl’:
./Modules/posixmodule.c:8775:13: warning: In the GNU C Library, "minor" 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 "minor", include <sys/sysmacros.h>
directly. If you did not intend to use a system-defined macro
"minor", you should undefine it after including <sys/types.h>.
return minor(device);
^~~~~~~~~~~~~
./Modules/posixmodule.c: In function ‘os_makedev_impl’:
./Modules/posixmodule.c:8793:13: warning: In the GNU C Library, "makedev" 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 "makedev", include <sys/sysmacros.h>
directly. If you did not intend to use a system-defined macro
"makedev", you should undefine it after including <sys/types.h>.
return makedev(major, minor);
