| I've never known ".ORDER".  This works for me:
| 
|       .ORDER: nodes.h nodes.c
| 
|       nodes.c nodes.h: mknodes.sh nodetypes nodes.c.pat
|               ${_MKTARGET_CREATE}

Yes, .ORDER is better. I wrote the .ORDER parser and I forgot about the
option to make it a target :-)

I tried:

nodes.c .ORDER nodes.h: mknodes.sh nodetypes nodes.c.pat

and of course it did not work.
