FIX: No C4051 Warnings Compiling .CPP or .CXX Files

SYMPTOMS

When Microsoft C/C++ compiles a source code file that has the .CPP or .CXX filename extension, the compiler does not generate any C4051 warning messages. However, when Microsoft C/C++ compiles a source code file that contains similar code but that has the .C filename extension, the compiler correctly generates C4051 warning messages as follows:

/*
 * Compile options needed: /W4
 */ 

void main()
{
   int i;

   i = 66.66 * 55.55;
}
