Switch 

Meaning 

-Vb  

Turn on all -Vb switches.  

-Vb+  

Turn on all -Vb switches.  

-Vb-  

Turn off all -Vb switches.  

-Vb.  

Reset all -Vb switches.  

-Vbe  

Allow old-style explicit template specialization.  

-Vbn  

Allow calling a non-const member function for a const object.  

-Vbo  

Use old overload resolution rules.  

-Vbr  

Allow non-const reference binding.  

-Vbs  

Do not treat string literals as const.  

-Vbx  

Allow explicit template specializations as member functions.  

General Compatibility options 

Description 

Non-const string literals (-Vbs) 

Do not treat string literals as const. Default = false  

Global functions in segments (-VA)* 

Generates all global functions in their own virtual or weak segment. Default = true  

Don't mangle calling convention (-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 does 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 = false  

Microsoft header search algorithm (-VI)* 

Uses Microsoft search algorithms to locate the header files. Default = true  

VC++ compatibility (-VM) 

To provide compatibility with Microsoft Visual C++ , substitutes __msfastcall for __fastcall calling convention. This switch should not be used when working with a VCL application. It causes numerous linker errors. Default = false  

Disable lexical digraph scanner (-Vg) 

Disables the lexical digraph scanner. Digraphs are two character sequences that stand in for a single character that may be hard to produce on certain keyboards. If this option is true, then such diagraphs are not recognized. Default = false  

Enable new operator names (-Vn) 

Enables new operator names such as 'and', 'or', 'and_eq', 'bitand', etc. Default = false  

Enable all compatibility options (-Vo) 

Sets most of the compatibility flags used with old code, enabling -Vv , -Va, -Vp, -Vt, -Vc, -Vd, and -Vx. Default = false  

Reverse Multi-character constants (-Vr) 

The compiler reverses the order of Multi-character constants. Default = false  

Old style virdef generation (-Vs) 

Uses old-style virdef generation. Default = false  

Native code for MBCS (-Vw) 

Emits native code instead of Unicode for multi-byte character. Default = false  

Old 8.3 include search (-Vi) 

Use old 8.3 search algorithm to locate header files. Default = false  

General option 

Description 

Default 

Saves the current settings as the default for each new project.
