  The purpose of this patch is to toggle the debugging mode (default) to
  Program Database (from Program Database for Modify on the fly debugging).

  The net effect of this patch is to clean up all of the irrelevant entries
  associated with either the debugging or release command line switches, and
  generally straighten the projects as they would be exported from VC6/SP5.

  The outcome of this patch is that VC5 users -should- be able to load and
  build the workspace without any errors (as they used to have no symbols
  database at all, the /ZI option doesn't work, they had to use cvtdsp.pl
  to toggle these to /Zi.)
