# identifiers used in ACE's preprocessor conditionals (generated with
# GNU Autoconf's "ifnames" program). The script will go through the list in
# ACE.ifnames and determine if the given macro was defined in only one of the
# two headers being headers being compared.
#
# The C++ pre-processor is used when comparing so that macros from "#included"
# headers will also be checked.
