This patch contains changes to the build (configure) system and the code
required to support the move.  The patch is provided to isolate the
changes from the others that follow it; the code won't necessarily
compile after this patch (the next changes are required.)

# CONTRIBUTED EXTENSIONS
#
# The following extensions are part of a standard libpng distribution. They are
# not supported parts of libpng and they are not necessarily released under the
# same license as libpng. Please consult the relevant directory for copyright
# and support information before uncommenting any of the lines below.
#
# After you change this file you MUST re-run "autoreconf" to regenerate the
# configure script, otherwise the change may have no effect.
#
# Include the ARM NEON extension:
#sinclude([contrib/neon/neon.ac])
#
# If any of the extensions require automake support (this is likely) automake
# must include the file contrib/extensions.am
#libpng_automake_extensions="yes"
