+# Makefile.config
+#
+# Common configuration and setup file to generate the ACPICA tools and
+# utilities: the iASL compiler, acpiexec, acpihelp, acpinames, acpisrc,
+# acpixtract, acpibin.
+#
+# This file is included by the individual makefiles for each tool.
+#
+
+#
+# Note: This makefile is intended to be used from within the native
+# ACPICA directory structure, from under generate/unix. It specifically
+# places all object files in a generate/unix subdirectory, not within
+# the various ACPICA source directories. This prevents collisions
+# between different compilations of the same source file with different
+# compile options, and prevents pollution of the source code.
+#
+
+#
+# Configuration
+#
+# OPT_CFLAGS can be overridden on the make command line by
+#   adding OPT_CFLAGS="..." to the invocation.
+#
+# Notes:
+#   gcc should be version 4 or greater, otherwise some of the options
+#     used will not be recognized.
+#   Optional: Set HOST to an appropriate value (_LINUX, _FreeBSD, _APPLE, _CYGWIN, etc.)
+#     See include/platform/acenv.h for supported values.
+#     Note: HOST is not nearly as important for applications as it
+#     is for the kernel-resident version of ACPICA, and it may
+#     not be necessary to change it.
