The original question was this: "what happens if one uses commercial
software licensed under the terms that imply that any software that
integrates in the software or is added to the software (or a larger work)
must be licensed under the same license is used with GPL licensed software."
It seems to me that there is nothing new here. As your example nicely
illustrates, your hypothetical involves a license that prohibits the
licensee from doing what he or she desires, which is to use free software or
software - - as apparently Microsoft views it - - offered under "an IPR
impairing license;" the potential consequence of  "mixing" the source code
is a [breach/infringement] of one or both [licenses/copyrights].
