Build the Debug MFC Libraries with Reduced CodeView Information
| Overview
Try rebuilding the MFC libraries using the /Zi compiler switch instead of /Z7. The /Zi option builds a program database (.PDB) file for the entire library that contains all of the symbolic type information. Each time the compiler generates type information for a new symbol when compiling the source files, it checks the .PDB file to see whether this type is already present. If so, the type is not added.
