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