Re: Supressing a %d parameter in a string

[dsplat rochester rr com]

I actually expected to get an error, so I tried it with gcc last night:

  printf( "arg %2$d, arg %3$d\n", 1, 2, 3 );

gcc didn't even feel a need to warn me.

I didn't try getting any of the gettext tools to accept it.  If they won't, we may want to consider whether it should be possible to tell them to treat it as a warning rather than an error.  I wouldn't make that the default behavior.  It is almost always an error to omit a parameter.  However, it would be nice to be able to override it when necessary.
