 * Environment configuration.  The purpose of this file is to interface to the
 * local generation environment.
 *
 * 1) ACPI_USE_SYSTEM_CLIBRARY - Define this if linking to an actual C library.
 *      Otherwise, local versions of string/memory functions will be used.
 * 2) ACPI_USE_STANDARD_HEADERS - Define this if linking to a C library and
 *      the standard header files may be used.
 *
 * The ACPI subsystem only uses low level C library functions that do not call
 * operating system services and may therefore be inlined in the code.
 *
 * It may be necessary to tailor these include files to the target
 * generation environment.
 *
 *
 * Functions and constants used from each header:
 *
 * string.h:    memcpy
 *              memset
 *              strcat
 *              strcmp
 *              strcpy
 *              strlen
 *              strncmp
 *              strncat
