Question
Recently I had some linking issues caused by the presence (or absence) of this flag.
/Zc:wchar_t-
I've read the docs, but they don't mention the trailing minus. But every discussion of it seems to include it. What does it mean?
Solution
/Zc:wchar_t-
does the opposite of what /Zc:wchar_t
does: it causes wchar_t
to be treated as the same type as unsigned short
, for compatibility with VC6.
/Zc:wchar_t-
causes your code to be non-conformant with standard C++, so don't use it unless you must.
