Ruby » Ruby 1.8

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: error: previous declaration of ‘BN_pseudo_rand_range’ was here

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.
