+dnl check the string type of the name of a filesystem mount table entry.
+dnl Usage: AC_CHECK_MNTTAB_TYPE(<fs>, [fssymbol])
+dnl Check if there is an entry for MNTTYPE_<fs> in sys/mntent.h and mntent.h
+dnl define MNTTAB_TYPE_<fs> to the string name (e.g., "nfs"). If <fssymbol>
+dnl exist, then define MNTTAB_TYPE_<fssymbol> instead. If <fssymbol> is
+dnl defined, then <fs> can be a list of fs strings to look for.
+dnl If no symbols have been defined, but the filesystem has been found
+dnl earlier, then set the mount-table type to "<fs>" anyway...
