I'm updating a product to use VC7 (VS .NET 2003). Our old build scripts use -O2 and -Ob1 in the command line. When I set optimization to /O2 in the IDE, the /Ob1 is left out of the build even though it appears in the property pages. Why can't I use these two settings in combination through the IDE.
