102 * Environment configuration. The purpose of this file is to interface to the
103 * local generation environment.
105 * 1) ACPI_USE_SYSTEM_CLIBRARY - Define this if linking to an actual C library.
106 * Otherwise, local versions of string/memory functions will be used.
107 * 2) ACPI_USE_STANDARD_HEADERS - Define this if linking to a C library and
108 * the standard header files may be used.
110 * The ACPI subsystem only uses low level C library functions that do not call
111 * operating system services and may therefore be inlined in the code.
113 * It may be necessary to tailor these include files to the target
114 * generation environment.
117 * Functions and constants used from each header:
