I haven't seen a non-static inline function defined in a common
header files.  Does this actually work?  In my build, ld choked on
this one.

This is quite subtle: "inline" is just a hint to the compiler but the

compiler can choose not to inline, so there must be an external symbol

to link to (which is not the case with this code).


My tests and the CI builds went smoothly, so I guess all these compilers

luckily chose to inline, but not yours.


With "static", we ensure that either it is inlined or there is a static

function (in which case, this bit of code will be duplicated across

compilation units).
