[MacTUG] Looking for IBM software for software audit

[Martin Timmerman]

Hello Mac users,

IBM is conducting a software audit at the University of Waterloo. Their 
records indicate some campus usage of the software product:

XL C/C++ Advanced Edition for Mac OS X

Does anyone on this MacTug group use the software, or know of any 
on-campus usage?

If so, are you able to tell me:
1) the version of the software in use
2) who is using the software

Many thanks for your help!

Martin Timmerman, IST
