When I compile a C-file which include headers that use the wchar_t native type, the compiler does not defined that type. However when the file is compiled as C++ the wchar_t native type is defined when the /Zc:wchar_t option is defined. Is that the expected behavior? There no information in the documentation that says if compiling as C the wchar_t native type is undefined. I have VS2012 Prof version 11.0.50727.1 RTMREL installed.

Details (expand)

Visual Studio 2012

Create a simple C-file that defines a global wchar_t variable. Compile as C-code and then compile as C++-code.

Thanks for the quick response. To continue my work, I put in the typedefs for the __wchar_t on the C code as a work-around. Now I working on a more pressing issue before I can get back to this. I am in the process of trying to move old .NET 2.0, managed/unmanaged C++ from VS2005 to VS2012 using .NET 4.0.
