[patch cygwin]: Replace inline-assembler in string.h by C implementation

Hello,

this patch replaces the inline-assember used in string.h by C implementation.
There are three reasons why I want to suggest this.  First, the C-code might
be optimized further by fixed (constant) arguments.  Secondly, it is
architecture
independent and so we just need to maintain on code-path.  And as
third point, by
inspecting generated assembly code produced by compiler out of C code
vs. inline-assembler
it shows that compiler produces better code.  It handles
jump-threading better, and also
improves average executed instructions.

ChangeLog

2012-10-24  Kai Tietz

	* string.h (strechr): Replace assembler by
	C code.
	(ascii_strcasematch): Likewise.
	(ascii_strncasematch): Likwise.

Ok for apply?

Regards,
Kai

Hmm, wouldn't assume so.  I can give JonY a ping for that.  I assume
he would provide such a package.  Shall I ask him?

[patch]: Decouple cygwin building from in-tree mingw/w32api building

Hello everybody,

This patch modifies the bits of build-process so that cygwin and mingw
building is decoupled from each other.
Additionally the patch decouples cygwin's build from the w32api of mingw.org.
By this change it is now possible to build cygwin (and utilities) with
mingw.org's and mingw-w64's psdk and compilers.  Later are necessary
to build cygwin's native utils, which have not to depend on
cygwin1.dll.
These changes are also necessary for having 64-bit build support in
future. By this reason the mingw-script in utils/ had to learn about
the host's architecture and about how to search for an installed
mingw-toolchain for given architecture.  As Corinna told me that
cygwin wants to use in question the -w64- mingw-environment, this
script is searching first for -w64- based toolchain.  On second
attempt it searches for any mingw triplet for given architecture.

ChangeLog winsup/

2012-10-17  Kai Tietz

	* Makefile.common: Remove w32api specific internal
	configure.
	(nostdincxx): Always turn off default libraries.
	* Makefile.in: Remove for cygwin build dependencies
	to w32api and mingw.
	* configure.in: Make test for w32api directory optional.

[PATCH] suggestion for faster pseudo-reloc.

This patch fixes the problem making pseudo-reloc too slow when there is 
many pseudo-reloc entries in rdata section by deciding when not to call 
Virtual{Query,Protect} to save overhead.
I tested this patch and time taken for pseudo-reloc reduced 1800ms to 
16ms for 3682 entries.
Please review this patch.

	* pseudo-reloc.cc (auto_protect_for): Define.
	(__write_memory): Use auto_protect_for, add verbose message displaying the number of items.

console: terminal request/response

This is another patch to enable terminal responses in the cygwin console.
Typically, terminals respond to requests to report Primary/Secondary 
Device Attributes
and to send a Cursor Position Report (see 
http://invisible-island.net/xterm/ctlseqs/ctlseqs.txt).
(This hasn't ever worked in the cygwin console except with obsolete 
setting CYGWIN=tty.)

My attached patch should now fix this. I know it's not really 
significant anymore
(http://cygwin.com/ml/cygwin-patches/2012-q2/msg00002.html) but I 
couldn't resist
to rework and fix my previous fix attempts.

[PATCH] Make `makewhatis` FAQ entry explicitly refer to `whatis`

All,

Minor FAQ patch below to make it explicit that `makewhatis` is used for
`whatis` as well as `man -k` and `apropos`. Inspired by someone [apparently
being confused][0] on Stack Overflow (yes, they were almost certainly being
lazy, but I figure being more explicit will do no harm).

[0]: http://stackoverflow.com/questions/11774230/unix-cygwin-whatis-returns-all-commands-as-nothing-appropriate/11782300#comment15656666_11782300

I'm hoping this doesn't count as "significant" with regard to copyright
assignment. I'd really rather not have to deal with that tedium.

This is my first submitted patch; I *think* I've got everything right, but
apologies if not.

2012-08-03  Adam Dinwoodie  <Adam.Dinwoodie <at> ...>

	* faq-using.xml (faq.using.man): Make relevance to whatis explicit.
