[openssl.org #2012] opensslconf.h #ifndef DES_RISC1

[Tony Weber via RT]

Regarding `openssl-0.9.8k.tar.gz' at http://www.openssl.org/source/

A snippet of opensslconf.h reads:

/* This helps C compiler generate the correct code for multiple functional
 * units.  It reduces register dependancies at the expense of 2 more
 * registers */
#ifndef DES_RISC1
#undef DES_RISC1
#endif

#ifndef DES_RISC2
#undef DES_RISC2
#endif

#if defined(DES_RISC1) && defined(DES_RISC2)
YOU SHOULD NOT HAVE BOTH DES_RISC1 AND DES_RISC2 DEFINED!!!!!
#endif

The first 2 parts seem to say `if it's not defined, then undefine it'.  Is
something like the following intended?:

#ifdef DES_RISC1
#undef DES_RISC2
#endif


Sorry if I've misunderstood the purpose of these lines.  Thanks for your
work on this software.
