Simply adding the include fixes the problem.

Note: this also compiles on glibc so its a harmless patch. Reproducible: Always Steps to Reproduce: 1. download any armv7a uclibc tarball from http://distfiles.gentoo.org/experimental/arm/uclibc/ 2. In a chroot try to upgrade to util-linux-2.24.1-r2 3. You should hit the bug.
once sec ... this is probably a uclibc issue with <sys/mount.h>. The following commit should fix it: http://git.uclibc.org/uClibc/commit/include/sys/mount.h?id=76ff037059f6d387bde9d540f7e27a2b376d7cd7 I'll test and report back.

(In reply to Anthony Basile from comment #2) that is the master branch. the 0.9.33 branch is 641a5356a021f90ee922229bd8e1aa6eafe152bc. i've added that to uclibc-0.9.33.2-r11 now. http://sources.gentoo.org/gentoo/src/patchsets/uclibc/0.9.33.2/18_all_mount.h.patch?rev=1.1
