MS C 6.0 LINK: how to suppress the Definitions File prompt?

[Colonel Panic]

With the new version of the MS linker, a prompt for a Definitions File
has been added.  As a result, linker response files created to work 
with the LINK that came with 5.1 don't work automatically -- the user
is prompted to specify a definition file (or hit return for the default
of no "deffile").  I would like to avoid the prompt altogether.  After
RTFMing carefully, I still can't see any way to suppress this via a
parameter (e.g. the LINK env variable).  Is there an undocumented
means of avoiding this prompt without changing the response files?

Please use email, and I will followup if I hear anything.
Thanks in advance.
