This may still contain a few errors from the old documentation,
but most of it should make sense.

Their solution for CRAY is somewhat awkward.
I'll assume that a "short" is 32 bits on CRAY to avoid the
#ifdef _CRAY
    typedef struct {
        unsigned int a:32;
        unsigned int b:32;
    } XXX;
#else
    typedef DES_LONG XXX;
#endif

that is actually used (even though it may not appear so at first
sight).

This was meant for building individual ciphers separately;
but nothing of this is maintained, it does not work
because we rely on central configuration by the Configure
utility with <openssl/opensslconf.h> etc., so the files
are only wasting space and time.

Never use des_set_key (it depends on the global variable des_check_key),

Only destest.c bothered to look at the return values of des_set_key,
but it did not set des_check_key -- if it had done so,
most checks would have failed because of wrong parity and
because of weak keys.

This will soon be complemented with MacOS specific source code files and

I (Andy) have decided to get rid of a number of #include <sys/types.h>.
I've verified it's ok (both by examining /usr/include/*.h and compiling)
on a number of Unix platforms. Unfortunately I don't have Windows box
to verify this on. I really appreciate if somebody could try to compile
it and contact me a.s.a.p. in case a problem occurs.
