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...

      If dynamically-loadable ENGINEs are linked against a shared-library version · 04dc4edb

      of libcrypto, then it is possible that when they are loaded they will share
the same static data as the loading application/library. This means it will
be too late to set memory/ERR/ex_data/[etc] callbacks, but entirely
unnecessary to try.

This change (and a great part of this comment) was implemented in
0.9.8-dev a long time ago, but slightly differently.  In 0.9.8-dev, a
specific function that just returns a pointer to some static object is
used. For 0.9.7x, we couldn't do that, since the way we handle feature
freezes is, among other, to not add any more non-static functions.
Instead, we use the function ERR_get_implementation() and compare the
returned value with fns->err_fns, a member of fns that already is
there, and which therefore can safely be used in this manner.

What happens is that if the loaded ENGINE's return value from this
function matches the loading application/library's return value - they
share static data. If they don't match, the loaded ENGINE has its own
copy of libcrypto's static data and so the callbacks need to be set.
