 MSDN -> Visual Studio 6.0 Docs -> Visual C++ Docs:
 
  /GB     Blend  Optimizes the code created to favor the Pentium. It
                 blends the optimizations for the 80386 (/G3), 80486
                 (/G4),   Pentium   (/G5),  and  Pentium  Pro  (/G6)
                 options.  This option forces a value of 500 for the
                 _M_IX86  preprocessor  macro.  This  value  is  the
                 default. Future versions of the compiler will issue
                 a   different   value   to   reflect  the  dominant
                 processor.

Best regards,
 Serge                            mailto:[EMAIL PROTECTED]
