155 * local generation environment.

157 * 1) ACPI_USE_SYSTEM_CLIBRARY - Define this if linking to an actual C library.
158 *      Otherwise, local versions of string/memory functions will be used.
159 * 2) ACPI_USE_STANDARD_HEADERS - Define this if linking to a C library and
160 *      the standard header files may be used.
161 *
162 * The ACPI subsystem only uses low level C library functions that do not call
163 * operating system services and may therefore be inlined in the code.
164 *
165 * It may be necessary to tailor these include files to the target
166 * generation environment.
