I am planning to use #ifdef SIZEOF__FLOAT16 to check whether _Float16 is available. Would you prefer a different mechanism?

that sounds reasonable. We should make sure that this is set in cmake/template/cpl_config.h.in so that code like out-of-tree drivers has also access to that define when building against GDAL headers

Should GetSrcVal in pixelfunctions.cpp return 0 for float16, or report an error if unsupported?
