84 * Environment configuration. The purpose of this file is to interface to the
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
105 * strcpy
106 * strlen
107 * strncmp
108 * strncat
