Subject: [PATCH] Fix the build on RHEL5, when libcap-devel is installed.

The /usr/include/sys/capability.h defines _LINUX_TYPES_H
which prevents /usr/include/linux/types.h from being parsed
(when included afterwards). Thus certain types are undefined
that are for instance needed in /usr/include/linux/dqblk_xfs.h.
This breaks the build of lib/sysquotas_xfs.c.

This commit adds a configure check and a workaround for this.

Michael
