That is to say that -Os also sets this according to [1]:

  It also enables -finline-functions, causes the compiler to tune
  for code size rather than execution speed, and performs further
  optimizations designed to reduce code size.

So it seems maybe some pieces of cake think inlining is done
whereas others do not.
This leads me to that terribline "inline" behaviour of ISO C all
in all. In C++ if a compilation unit needs that thing or an
address thereof it simply creates an instance, damn. And
_Static_assert is also c..p compared to C++ static_assert or so.
S....y d..n ISO C decisions, all over the place.
