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...

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.

this change no longer "fixes" the bn_print.c functions, but it makes for
cleaner code. This patch was a part of ticket 697.

can lead to corruption. This change allows all bignum tests to pass with
BN_DEBUG and BN_DEBUG_RAND debugging and valgrind. NB: This should be
tested on a few different architectures and configuration targets, as the
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).
