--- Comment #10 from M Welinder <terra at gnome dot org> ---
mystrlen and strlen are not equivalent, so gcc is wrong in turning the former
into a call of the latter.
Specifically: mystrlen preserves errno, strlen need not do that. (C99 section
7.5 item 3.)
(Repeating the comment from over in bug 56888.)
