According to the C11 standard, char32_t and char16_t are not part
of the C language but are part of the C library and have to be declared in <uchar.h> - see paragraph 7.28.2. In stark contrast, according to the C++11 standard, char32_t and char16_t are part of the C++ language, namely, keywords - see paragraph 2.12.1. Consequently, they must not be declared in a header file. To resolve this vile contradiction, use the predefined macro __cplusplus to find out which language is in use for the current compilation unit - see C11 paragraph 6.10.8.3 and C++11 paragraph 16.8.1. Reminded of the problem by naddy@. OK naddy@ who tested in make build / make release. Looks reasonable to millert@.
