#
# acpisrc - ACPICA source code conversion utility
#
# NOTE: This makefile is intended to be used in the Linux environment,
# with the Linux directory structure. It will not work directly
# on the native ACPICA source tree.
#

#
# Configuration
# Notes:
#   gcc should be version 4 or greater, otherwise some of the options
#       used will not be recognized.
#   Global optimization flags (such as -O2, -Os) are not used, since
#       they cause issues on some compilers.
#   The _GNU_SOURCE symbol is required for many hosts.
