 102 * Environment configuration.  The purpose of this file is to interface to the
 103 * local generation environment.
 104 *
 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.
 109 *
 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.
 112 *
 113 * It may be necessary to tailor these include files to the target
 114 * generation environment.
 115 *
 116 *
 117 * Functions and constants used from each header:
 118 *
 119 * string.h:    memcpy
 120 *              memset
 121 *              strcat
 122 *              strcmp
 123 *              strcpy
 124 *              strlen

 126 *              strncat
