I just traced a linker problem I was having to a difference between some libraries and the Qt VS addin default settings on Windows.

the library, xerces-c, is compiled with intrinsic/ builtin wchar_t, while Qt by default uses an external wchar_t implementation.

I can overcome the linker errors by forcing Qt to use builtin wchar_t, but the app seems to have some quirks that I don't remember-

Does Qt need the external specification of Qt? can I recompile Qt to support built-in wchar_t ?

Should I expect quirks from the change between builtin and external-

- Thanks for the help...
