You can also use the option `-Winline' to have the compiler warn you if some
function you declare `inline' cannot be.

This is also what the docs say. Some amplification:
* The flag you are interested in is `-finline'. `-finline-functions' makes
the compiler attempt to inline ALL functions.
* `-finline' is turned on by all `-O' options by default, so you shouldn't
need to use it at all.

Version 2.7.2.1 still said in the documentations that this restriction
applied. Perhaps it is inaccurate though, I don't know. It would be wise to
define the function before you use it.
