Submitter's comment:

This patch:

a) Introduces a new file os2/backwardify.pl.

b) Introduces a new mk1mf.pl variable $preamble.  As you can see, it may
   be used also to move some OS-specific code to VC-CE too (the the
   first chunk of the patch);

c) The DESCRIPTION specifier of the .def file is made more informative:
   now it contains the version number too.  On OS/2 it is made conformant
   to OS/2 conventions; in particular, when one runs the standard command
	BLDLEVEL this.DLL
   one can see:

   Vendor:      www.openssl.org/
   Revision:    0.9.7c
   Description: OpenSSL: implementation of Secure Socket Layer; DLL for library crypto.  Build for EMX -Zmtd

   [I did not make Win32 descriptions as informative as this - I'm afraid to
    break something.  Be welcome to fix this.]

d) On OS/2 the generated DLL was hardly usable (it had a shared initialized
   data segment).

e) On OS/2 the generated DLLs had names like ssl.dll.  However, DLL names on
   OS/2 are "global data".  It is hard to have several DLLs with the same
   name on the system.  Thus this precluded coexistence of OpenSSL with DLLs
   for other SLL implementations - or other name clashes.  I transparently
   changed the names of the DLLs to open_ssl.dll and cryptssl.dll.

f) The file added in (a) is used to create "forwarder" DLLs, so the
   applications expecting the "old" DLL names may use the new DLLs
   transparently.  (A presence of these DLLs on the system nullifies (e),
   but makes old applications work.  This is a stopgap measure until the
   old applications are relinked.  Systems with no old applications do not
   need these DLLs, so may enjoy all the benefits of (e).)

   The new DLLs are placed in os2/ and os2/noname subdirectories.

g) The makefiles created with os2/OS2-EMX.cmd did not work (some mysterious
   meaningless failures).  The change to util/pl/OS2-EMX.pl uses the
   variable introduced in (b) to switch the Makefiles to SHELL=sh syntax.
   All these backslashes are removed, and the generated Makefiles started to
   work.

h) Running os2/OS2-EMX.cmd now prints out what to do next.

to apps.c, and give it the hopefully descriptive name parse_yesno().

rationale behind the move is that it's use by several applications.
The rationale behind the name change is that it describes what the
function does a bit better.

bignum code this deals with is quite preprocessor (and assembly) sensitive.

first of these two loops was off-by-one (copying one too many values). This
change also removes a superfluous assignment that would set an unused word
to zero (and potentially allow an overrun in some cases).
