/* This definition is only used if inlining fails for this function; see
the last page of <sys/stat.h>. The real work is done by the `x'
function which is passed a version number argument. We arrange in the
makefile that when not inlined this function is always statically
linked; that way a dynamically-linked executable always encodes the
version number corresponding to the data structures it uses, so the `x'
functions in the shared library can adapt without needing to recompile
all callers. */
