-Subject: [PATCH 21/29] Port AC_FUNC_MMAP to more-modern systems
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-* lib/autoconf/functions.m4 (AC_FUNC_MMAP): Don’t call
-getpagesize, as it’s tricky to configure, modern POSIX doesn’t
-require it, and calling it without including <unistd.h> provokes a
-compile-time error on modern systems.  Instead, rework the test
-to not need getpagesize.  Add a FIXME comment for unnecessary
-tests; I don't want to remove them now as we're too close to
-a release.  Remove long-obsolete comment about GNU grep.

-Upstream-Status: Backport
