I posted this a few months ago in a different form, and I am not sure anyone
responded.

If you name your solution configuration with a one letter name (like D or R)
it is not saved in the solution file in the following section (i.e. on save
the lines describing the configurations disappear):

GlobalSection(SolutionConfiguration) = preSolution
EndGlobalSection

If I use a longer name, like Debug or even DD it works:

GlobalSection(SolutionConfiguration) = preSolution
 Debug = Debug
 Release = Release
EndGlobalSection

This prevents other tools like Incredibuild from working correctly.
