dnl    Set shell variable ext2fs_undel to "yes" if we have it,

dnl MC_VFS_CHECKS
dnl   Check for various functions needed by libvfs.
dnl   This has various effects:
dnl     Sets MC_VFS_LIBS to libraries required
dnl     Sets vfs_flags to "pretty" list of vfs implementations we include.
dnl     Sets shell variable use_vfs to yes (default, --with-vfs) or
dnl        "no" (--without-vfs).
dnl     Calls AC_SUBST(mcserv), which is either empty or "mcserv".
