The current file-set, downloaded from openssl.org on 5 May 2000 fails to build
on SunOS 4.1.4. Hardware is SPARC, obviously. Same results with cc and gcc.
There are three routines used in the code-set that do not exist in this O/S
environment.
strtoul(), used in crypto/asn1/a_strnid.c
strerror(), used in crypto/err/err.c
and
memmove(), used in /bio/bss_mem.c, bio/bss_rtcp.c, exp/bio_ok.c, and
ssl/s3_pkt.c
The following additional code is a functional work-around, without touching
any of the existant source. 2 changes required to Makefiles. a reference
for this routine must be added in the OBJS list in apps/Makefile, and the
'test' code also requires this routine. ( I took the 'lazy' way out on that,
and just added it to the LIBCRYPTO= directive -- sloppy, but effective :)
The -right- way to handle these dependencies is with tests in the configure
script, and #ifdef'd code in the offending source files.
'Somebody' already did a patch on crypto/stack/stack.c that removed a call
to memmove(), and substituted a in-line copy loop. with comment that
"memmove() doesn't exist on SunOS 4.1.3 :( ".
_That_ patch is badly done. The old code is 'commented out' vi an
"#ifdef undef", and the new code is inserted _unconditionally_. If someone
were to try to use the other code, by "merely" #define-ing 'undef', they'd
get the copy operation _twice_ -- with catastrophic results, as this use is
essentially a 'one-character right-shift' of the string.
Either the old code should be removed completely, relying on CVS for the
'history', or the two code-paths should be in an #ifdef / #else / #endif
structure -- such that one option, and *only* one option, gets compiled in.

to += len;
from += len;
while (len--)

return(s1);
}
