Hi Vincente,

Thanks for looking at this.

I think this TI compiler doesn't inline anything not marked inline.
Additionally it doesn't seem to inline constructors, unless marked

So if there aren't any thoughts against this, I suggest all constexpr
functions in duration and time_point to be marked inline, and constexpr
constructors to be marked forceinline. Or should I just touch the cases,
that need to be inline in my example situation? I'd prefer the former ;-)

I'll create a ticket and supply a patch shortly.


[1] The TI compiler supports the GCC extension attribute forceinline.
