70 * Environment configuration. The purpose of this file is to interface to the
71 * local generation environment.
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 *
81 * It may be necessary to tailor these include files to the target
82 * generation environment.

85 * Functions and constants used from each header:

87 * string.h: memcpy
88 * memset
89 * strcat
90 * strcmp
91 * strcpy
92 * strlen
93 * strncmp
94 * strncat
