What a load of bull, how long does it take to change the .rc files, using an existing .rc (e.g. from ipoib) as an example?  5 minutes?  This is just another example of how WinOF is treated as a dumping ground/out house by Mellanox.  Seriously, WTF.

I originally added the 'd' suffix because of mismatches.  Without them, you must always run a homogeneous stack, so you can't debug an app without flipping everything to debug.  If you flip the whole stack, you must also flip any applications that might have a dependency.

I would suggest rolling back the change for RC3, and just not shipping the debug bits - only install the release bits, and provide a zip file with the debug DLLs to facilitate development (do we have an SDK package)?

Alternatively, maybe only complib has the problem - I haven't checked to see if IBAL, WinVerbs, etc. have ABI issues with structures changing sizes between release and debug builds.  If complib is the only one, we might be better off making it a static library rather than a DLL, and avoid the whole problem that way.

Cheers,
-Fab
