Sounds good. This would mean od could work even the platform doesn't

Oh, and another thought: suppose someone wants to use od on bfloat16_t
values? They're popular in machine learning applications, and likely
will be more popular than float16_t overall. See:

Thanks for writing that. One suggestion I'd make is to change this:
#ifndef FLT16_MAX
/* This is just a place-holder to avoid a few '#if' directives.
In this case, the type isn't actually used. */
typedef float _Float16;
#endif
to something like this:
#ifdef FLT16_MAX
typedef
