  89  * Environment configuration.  The purpose of this file is to interface to the
  90  * local generation environment.
  91  *
  92  * 1) ACPI_USE_SYSTEM_CLIBRARY - Define this if linking to an actual C library.
  93  *      Otherwise, local versions of string/memory functions will be used.
  94  * 2) ACPI_USE_STANDARD_HEADERS - Define this if linking to a C library and
  95  *      the standard header files may be used.
  96  *
  97  * The ACPI subsystem only uses low level C library functions that do not call
  98  * operating system services and may therefore be inlined in the code.
  99  *
 100  * It may be necessary to tailor these include files to the target
 101  * generation environment.
 102  *
 103  *
 104  * Functions and constants used from each header:
 105  *
 106  * string.h:    memcpy
 107  *              memset
 108  *              strcat
 109  *              strcmp
 110  *              strcpy
 111  *              strlen
 112  *              strncmp
 113  *              strncat
 114  *              strncpy
 115  *
 116  * stdlib.h:    strtoul
