Yeah, but...

The AC_PREREQ only checks for the minimum required autoconf version for
*this* specific autoconf file.  AC_PREREQ([2.52]) doesn't mean we have to
use 2.52, but any later version will suffice.  All current autoconf
files are compatible with 2.69.  Neither binutils-gdb, nor gcc changed
their files to require 2.69.  So it's note quite clear to me what this
patch accomplishes.

Autoconf 2.71 is the next version introducing backward incompatibilities.
Wouldn't it make more sense to fix up the incompatibilities (if any)
and update the affected files to 2.71 to be more future-proof?
