[stunnel-users] engine-patch

Hi,

we have a the following openssl:

---
OpenSSL 0.9.7d 17 Mar 2004
built on: Wed Nov  3 13:28:35 CET 2004
platform: solaris-sparcv9-gcc
options:  bn(64,32) md2(int) rc4(ptr,char) des(idx,cisc,16,long) idea(int) blowfish(ptr) 
compiler: gcc -DOPENSSL_SYSNAME_ULTRASPARC -DOPENSSL_THREADS -D_REENTRANT -DDSO_DLFCN -DHAVE_DLFCN_H -DOPENSSL_NO_KRB5 -DOPENSSL_NO_ENGINE -m32 -mcpu=ultrasparc -O3 -fomit-frame-pointer -Wall -DB_ENDIAN -DBN_DIV2W -DMD5_ASM
---

We don't have the engine enabled therefore the current stunnel don't
compile :-(

I have attached the patch for the current (4.06) stunnel version.

BTW: I need the 'X-Forwarded-For' header, in where is the right position
     to add it in the 4.06 version. I think in 'src/client.c => transfer()'
     but i'am not sure, where there ;-)

Thanx for help ;-)

al ;-)
