[daip] Question about DDTs

[Sally Laurent-Muehleisen]

Hi Eric,

	Many, many thanks for your quick response.  I really appreciate it.
Just a couple comments:

We aren't using public catalogs.  They are all private.

Yeah, I just hadn't gotten around to setting this yet.  I'll set it to something
reasonable now.

Okay, we'll give this a try.  Thanks!

Yeah, but I couldn't get it to do anything *past* the aborting of IMAGR.
Previous to this, I think it runs a UVSRT and a UVDIF, but then IMAGR
comes next and everything just died at that point...we'll try recompiling
with something like a -fno-automatic option and see what happens.

					Thanks!
