(Command-line switch: -VC)

When this option is set, the compiler disables the distinction of function names where the only possible difference is incompatible code generation options. For example, with this option set, the linker will not detect if a call is made to a _ _fastcall member function with the cdecl calling convention.

This option is provided for backward compatibility only; it lets you link old library files that you cannot recompile.

Default = OFF
