+Building OpenSSL under Win32.
+
+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 modification.
+See the end of this file for Eric's original comments.
+
+You will need perl for Win32 (which can be got from various sources) and Visual
+C++.
+
+If you are compiling from a tarball or a CVS snapshot then the Win32 files may
+well be not up to date. This may mean that some "tweaking" is required to get
+it all to work. See the trouble shooting section later on for if (when?) it
+goes wrong.
+
+Firstly you should run Configure:
+
+perl Configure VC-WIN32
+
+Then rebuild the Win32 Makefiles and friends:
+
+ms\do_ms
+
+if you get errors about things not having numbers assigned then check the
+troubleshooting section: you probably wont be able to compile it as it stands.
+
+then from the VC++ environment at a prompt do:
+
+nmake -f ms\ntdll.mak
+
+you may get a warning about too many rules but if all is well it should all
+compile and you will have some DLLs and executables in out32dll.
+
+Troubleshooting.
+
+Since the Win32 build is only occasionally tested it may not always compile
+cleanly.
+
+If you get an error about functions not having numbers assigned when you
+run ms\do_ms then this means the Win32 ordinal files are not up to date. You
+can do:
+
+perl util\mkdef.pl crypto ssl update
+
+then ms\do_ms should not give a warning any more. However the numbers that get
+assigned by this technique may not match those that eventually get assigned
+in the CVS tree: so you anything linked against this version of the library
+may need to be recompiled.
+
+If you get errors about unresolved externals then this means that either you
+didn't read the note above about functions not having numbers assigned or
+someone forgot to add a function to the header file.
+
+In this latter case check out the header file to see if the function is defined
+in the header file: it should be defined twice: once with ANSI prototypes and
+once without. If its missing from the non ASNI section then add an entry for
+it: check that ms\do_ms now reports missing numbers and update the numbers as
+above.
+
+If you get warnings in the code then the compilation will halt.
+
+The default Makefile for Win32 halts whenever any warnings occur. Since VC++
+has its own ideas about warnings which don't always match up to other
+environments this can happen. The best fix is to edit the file with the warning
+in and fix it. Alternatively you can turn off the halt on warnings by editing
+the CFLAG line in the Makefile and deleting the /WX option.
+
+Finally you might get compilation errors. Again you will have to fix these or
+report them.
+
+Tweaks.
+
+There are various changes you can make to the Win32 compile environment. If you
+have the MASM assembler 'ml' then you can try the assembly language code. To
+do this remove the 'no-asm' part from do_ms.bat.
+
+You can also build a static version of the library using the Makefile ms\nt.mak
