22 the last page of <sys/stat.h>. The real work is done by the `x'
23 function which is passed a version number argument. We arrange in the
24 makefile that when not inlined this function is always statically
25 linked; that way a dynamically-linked executable always encodes the
26 version number corresponding to the data structures it uses, so the `x'
27 functions in the shared library can adapt without needing to recompile
