  85  * local generation environment.
  86  *
  87  * 1) ACPI_USE_SYSTEM_CLIBRARY - Define this if linking to an actual C library.
  88  *      Otherwise, local versions of string/memory functions will be used.
  89  * 2) ACPI_USE_STANDARD_HEADERS - Define this if linking to a C library and
  90  *      the standard header files may be used.
  91  *
  92  * The ACPI subsystem only uses low level C library functions that do not call
  93  * operating system services and may therefore be inlined in the code.
  94  *
  95  * It may be necessary to tailor these include files to the target
  96  * generation environment.
  97  *
  98  *
  99  * Functions and constants used from each header:
 100  *
 101  * string.h:    memcpy
 102  *              memset
 103  *              strcat
 104  *              strcmp
