AC_CHECK_PROG_VER(SED, sed, --version,
  [GNU sed version \([0-9]*\.[0-9.]*\)],
  [3.0[2-9]*|3.[1-9]*|[4-9]*],
  SED=: aux_missing="$aux_missing sed")

So its not really autoconf's fault, its glibc's configure.in.

glibc's configure.in could be patched but then the configure and
Makefile's would have to be rebuilt with the ancient and unsupported
autoconf version they use.

I guess the test could be patched out directly in configure, but the
patch would probably be version specific.

If lots of other programs do similar checks for GNU sed than maybe a
patch like yours would be a reasonable short to medium term solution.

Would be better if upstream packages fixed their build scripts.
