86 * Environment configuration. The purpose of this file is to interface to the
87 * local generation environment.
88 *
89 * 1) ACPI_USE_SYSTEM_CLIBRARY - Define this if linking to an actual C library.
90 * Otherwise, local versions of string/memory functions will be used.
91 * 2) ACPI_USE_STANDARD_HEADERS - Define this if linking to a C library and
92 * the standard header files may be used.
93 *
94 * The ACPI subsystem only uses low level C library functions that do not call
95 * operating system services and may therefore be inlined in the code.
96 *
97 * It may be necessary to tailor these include files to the target
98 * generation environment.
99 *
100 *
101 * Functions and constants used from each header:
102 *
103 * string.h: memcpy
104 * memset
105 * strcat
106 * strcmp
107 * strcpy
108 * strlen
109 * strncmp
110 * strncat
111 * strncpy
112 *
113 * stdlib.h: strtoul
114 *
115 * stdarg.h: va_list
116 * va_arg
117 * va_start
118 * va_end
