+dnl This macro will find out how to get mount point information if possible.
+dnl
+dnl The following defines will be set as appropriate:
+dnl HAVE_MOUNTS
+dnl HAVE_MNTENT_H
+dnl HAVE_SYS_MNTTAB_H
+dnl HAVE_SYS_MOUNT_H
+dnl HAVE_STRUCT_MNTENT_MNT_DIR
+dnl HAVE_STRUCT_MNTTAB_MNT_MOUNTP
+dnl HAVE_STRUCT_STATFS_F_MNTONNAME
+dnl HAVE_STRUCT_STATVFS_F_MNTONNAME
+dnl Also ACTION-IF-TRUE and ACTION-IF-FALSE are run as appropriate
