  Heres a few comments about building OpenSSL in Windows environments.  Most
  of this is tested on Win32 but it may also work in Win 3.1 with some

+ 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.
