Rename INSTALL.W32 to INSTALL.WIN

Also remove the INSTALL.W64 file. Next commit will update INSTALL.WIN to
cover both.

- INSTALLATION ON THE WIN64 PLATFORM
- ----------------------------------
-
- Caveat lector
- -------------
-
- As of moment of this writing Win64 support is classified "initial"
- for the following reasons.
-
- - No assembler modules are engaged upon initial 0.9.8 release.
- - API might change within 0.9.8 life-span, *but* in a manner which
-   doesn't break backward binary compatibility. Or in other words,
-   application programs compiled with initial 0.9.8 headers will
-   be expected to work with future minor release .DLL without need
-   to re-compile, even if future minor release features modified API.
- - Above mentioned API modifications have everything to do with
-   elimination of a number of limitations, which are normally
-   considered inherent to 32-bit platforms. Which in turn is why they
-   are treated as limitations on 64-bit platform such as Win64:-)
-   The current list comprises [but not necessarily limited to]:
-
-   - null-terminated strings may not be longer than 2G-1 bytes,
-     longer strings are treated as zero-length;
-   - dynamically and *internally* allocated chunks can't be larger
-     than 2G-1 bytes;
-   - inability to encrypt/decrypt chunks of data larger than 4GB
-     [it's possibly to *hash* chunks of arbitrary size through];
-
-   Neither of these is actually big deal and hardly encountered
-   in real-life applications.
-
- Compiling procedure
- -------------------
-
- You will need Perl. You can run under Cygwin or you can download
- ActiveState Perl from http://www.activestate.com/ActivePerl.
-
- You will need Microsoft Platform SDK, available for download at
- http://www.microsoft.com/msdownload/platformsdk/sdkupdate/. As per
- April 2005 Platform SDK is equipped with Win64 compilers, as well
- as assemblers, but it might change in the future.

- To build for Win64/x64:
-
- > perl Configure VC-WIN64A
- > ms\do_win64a
- > nmake -f ms\ntdll.mak
- > cd out32dll
- > ..\ms\test
-
- To build for Win64/IA64:
-
- > perl Configure VC-WIN64I
- > ms\do_win64i
- > nmake -f ms\ntdll.mak
- > cd out32dll
- > ..\ms\test
-
- Naturally test-suite itself has to be executed on the target platform.
-
- Installation
- ------------
-
- TBD, for now see INSTALL.W32.
