/* "soft" inline :
* The compiler is free to select if it's a good idea to inline or not.
* The main objective is to silence compiler warnings
* when a defined function in included but not used.
*
* Note : this macro is prefixed `MEM_` because it used to be provided by `mem.h` unit.
* Updating the prefix is probably preferable, but requires a fairly large codemod,
* since this name is used everywhere.
