[Bug-gnulib] mountlist merge from coreutils

[Paul Eggert]

I installed this:

2004-03-30  Jim Meyering  <address@hidden>

        * lib/mountlist.c [HAVE_SYS_UCRED_H]: Include grp.h before sys/ucred.h.

        Avoid a configure-time warning about sys/ucred.h on OSF V4.0.
        * m4/ls-mntd-fs.m4: Test for sys/ucred.h separately, since
        on some systems one must include <grp.h> before it.
        Reported by Christian Krackowizer.
