# DESCRIPTION
# This build definition file sets the ADRS_MACROS and ADRS_DEFINE build macros.
#
# The ADRS_MACROS build macro list the build macros the kernel configuration
# tool will have to get from cdf files, and write in the kernel configuration
# Makefile.
#
# The ADRS_DEFINE build macros is part of the CC_DEFINES, and is passed to the
# compilers as a definition macro
#
# TREE
# This file is included by :

# default values for some later comparisons
