commit 4da63c5881f60f71999a943612da9112232b9161
Author: Eric Blake <eblake@redhat.com>
Date: 2016-09-14 19:21:42 -0500
mountlist: include sysmacros.h for glibc
On Fedora rawhide (glibc 2.25), './gnulib-tool --test mountlist'
reports:
../../gllib/mountlist.c: In function 'read_file_system_list':
../../gllib/mountlist.c:534:13: warning: '__makedev_from_sys_types' is deprecated:
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 #undef it after including <sys/types.h>.
[-Wdeprecated-declarations]
me->me_dev = makedev (devmaj, devmin);

/usr/include/sys/sysmacros.h:89:1: note: declared here
__SYSMACROS_DEFINE_MAKEDEV (__SYSMACROS_FST_IMPL_TEMPL)
^
Fix it by including the right headers. We also need a fix to
autoconf's AC_HEADER_MAJOR, but that's a separate patch.
* m4/mountlist.m4 (gl_PREREQ_MOUTLIST_EXTRA): Include
AC_HEADER_MAJOR.
* lib/mountlist.c (includes): Use correct headers.
