  72  *
  73  * 1) ACPI_USE_SYSTEM_CLIBRARY - Define this if linking to an actual C library.
  74  *      Otherwise, local versions of string/memory functions will be used.
  75  * 2) ACPI_USE_STANDARD_HEADERS - Define this if linking to a C library and
  76  *      the standard header files may be used.
  77  *
  78  * The ACPI subsystem only uses low level C library functions that do not call
  79  * operating system services and may therefore be inlined in the code.
  80  *

  82  * generation environment.
