The only acpica tool that requires multithread support is
acpiexec. Along with previous changes to the actual source code,
this change removes unnecessary use of threading libraries.
It takes some effort to disable the MS language extensions because
of bugs in the MS headers, and the MS remapping of the low I/O
functions (open, read, write, etc.)
Conditionally compile the multi-thread support so that threading
libraries will not be linked if not necessary. The only tool
that requires multi-thread support is AcpiExec.
Disable language extensions where possible for maximum portability.
Unfortunately, when MS system includes are used, this option
cannot be used (oswinxf.c)
Update purpose of the makefile and add a warning that these makefiles
are only suitable for generation within the native ACPICA directory
structure (which is different than Linux, for example.)

We can only sort the _TSS return package if there is no _PSS in the
same scope. This is because if _PSS is present, the ACPI specification
dictates that the _TSS Power Dissipation field is to be ignored, and
therefore some BIOSs leave garbage values in the _TSS Power field(s).
In this case, it is best to just return the _TSS package as-is.
Runtime option can be used to disable return value repair if this
is causing a problem on a particular machine. Also added an option
to AcpiExec (-dr) to set this disable flag.
Now, only allow "SSDT" "OEM", and a null signature.
History:
1) Originally, we checked the table signature for "SSDT" or "PSDT".
2) We added support for OEMx tables, signature "OEM".
3) Valid tables were encountered with a null signature, so we just
gave up on validating the signature, (05/2008).
4) We encountered non-AML tables such as the MADT, which caused
interpreter errors and kernel faults. So now, we once again allow
only "SSDT", "OEMx", and now, also a null signature. (05/2011).
Always setup all arguments required by the method, even if the
command line specifies no arguments, or insufficient arguments.
Use "default" values for the missing arguments.
Also fixes a bug where only 6 method arguments were supported by
these commands instead of the maximum 7 arguments.
Now that DTC has full expression support, we don't want to have comment
strings that start with a paren or a less-than symbol. Now, only the
standard /* and // comments are supported, as well as the bracket []
comments.
Allow generic data types in custom acpi tables.
Field names are now optional.
Any line can be split to multiple lines using continuation char (\).
Large buffers now use line-continuation char and no colon on the
continuation lines.
