I've been experimenting with the Intel compiler for the past few weeks, and decided to go back to the VC++ compiler. I right clicked on the solution and selected "use vc++" compiler. Tried to build, and got a bunch of warnings about "ignoring unknown option /fast". I uninstalled the Intel compiler, completely blew away the development directly, got latest from source control, and the warnings are still there. I searched all of the files in the dev directory (including property sheets and project settings) for the /dev flag. Nothing.
Where else could the setting be coming from? None of the other command line options that I had entered are showing up, just /fast.
