Problem not in API, but in language: 1. wchar_t must not be defined when we
use headers in __cplusplus mode by
TenDRA.
(on SCO_SV it was the main problem)
2. The same with bool
3. all variables must have linked type.
4. empty blocks in C++ {}; now is illegal, I'm not shure,
is our _BEGIN_DECL and _END_DECL do the correct things.

Yes.
