# When modifying this file, configure.ac, the person making the changes
# should use autoconf 2.59 to regenerate the configure script.  Both
# configure.ac and configure should be checked in to subversion.  This is
# so that developers or users can build open64 without needing autoconf on
# their systems.

# It may be necessary from time to time to also update some of the files
# used by autoconf.  These are config.guess, config.sub, install-sh.
# The official versions of these three files are actually part of automake
# (which open64 does not use).  If any of these files need updating, the
# required change should be made to the latest automake sources first
# (if they are not already there) and then the files should be copied
# from the automake sources to our source tree.  Our versions of these
# files should always match some version of the automake sources and
# not diverge by having local changes in them.
