Bug #1174: compilation error with OpenSSL 0.9.8j
http://redmine.ruby-lang.org/issues/show/1174

Author: Michal Babej
Status: Open, Priority: Normal
Target version: Ruby 1.8.6
ruby -v: ruby 1.8.6 (2008-08-11 patchlevel 287) [x86_64-linux]

On an x86_64 system with openssl 0.9.8j, ruby-1.8.6-p287 fails to build 
openssl extension:

compiling openssl
make[1]: Entering directory `/home/mike/ruby-1.8.6-p287/ext/openssl'

/usr/lib/gcc/x86_64-unknown-linux-gnu/4.3.3/include-fixed/openssl/bn.h:421:

I have tracked down the problem here:
http://cvs.openssl.org/filediff?f=openssl/crypto/bn/bn.h&v1=1.125&v2=1.126

ruby 1.8.7 builds without error.
