The Autoconf philosophy is to check for system features, not for
system versions.  If the system has a C library that includes a
snapshot of the GLIBC regex code for example, we would still want to
use the gnulib version instead of the stale snapshot, even if the
library we were using, not actually being glibc, didn't #define the
same version symbols as glibc does.
