* _Float16 type to avoid issues when compiling the library
* with the -pedantic flag or similar where we get warnings
* about _Float16 not being an ISO C type.
*
* Due to the inclusion of H5private.h from the C++ wrappers,
* this typedef creation must be avoided when __cplusplus is
* defined to avoid build failures on ARM64 Macs. GCC and
* Clang either do not currently provide a _Float16 type for
* C++ on ARM64, or may need an additional compile-time flag.
