Ive got Vis C++ 2003  standard edition.   I want to optimize my application
for speed (use the /O2 directive).

The "optimization" field in my Project Properties window shows /O2 (in my
Release build)  but it is dimmed out.  I cannot change it.

My BuildLog.htm file says "Optimization not available in Vis C++ standard
edition.  This seems to imply that I have to buy Vis  C++ Professional
edition to get optimization.

I looked on the web, and some sites say that if you download the 2003 Vis
C++ Toolkit, it will contain updated C++ compiler files that include
optimization.,  I downloaded it, but the files are identical to the Vis C++
compiler I already have on my system.

I looked on the Microsoft web site for the Professional edition features,
and it says nothing about "includes additional optimization abilities above
the Standard edition".  

Thanks in advance for any replies,
