Compiler Warning C4430
This error can be generated as a result of compiler conformance work that was done for Visual C++ 2005: all declarations must now explicitly specify the type; int is no longer assumed. See Breaking Changes in the Visual C++ 2005 Compiler for more information.
C4430 is always issued as an error. You can turn off this warning with the #pragma warning or /wd; see warning or /w, /Wn, /WX, /Wall, /wln, /wdn, /wen, /won (Warning Level) for more information.
