Bob Moore 2147d3f00f ACPICA: Update for new gcc-4 warning options
Added several new options for the gcc-4 generation, and updated
the source accordingly. This includes some code restructuring to
eliminate unreachable code, elimination of some gotos, elimination
of unused return values, and some additional casting.

* Environment configuration. The purpose of this file is to interface to the

*
* 1) ACPI_USE_SYSTEM_CLIBRARY - Define this if linking to an actual C library.
* Otherwise, local versions of string/memory functions will be used.
* 2) ACPI_USE_STANDARD_HEADERS - Define this if linking to a C library and
* the standard header files may be used.
*
* The ACPI subsystem only uses low level C library functions that do not call
* operating system services and may therefore be inlined in the code.
*
* It may be necessary to tailor these include files to the target
* generation environment.
*
*
* Functions and constants used from each header:
*
* string.h: memcpy
* memset
* strcat
* strcmp
* strcpy
* strlen
* strncmp
* strncat
* strncpy
*
* stdlib.h: strtoul
