His own words are:
The patch adds no new functionality (other than a simple test package)
to the libraries, but it allows them to be compiled with Perl5.6.0.
It has only been tested under "Red Hat Linux release 7.0 (Guinness)"
with the unpatched verion of OpenSSL 0.9.6 released last September.
- ported BN stuff to OpenSSL's different BN library
- made the perl/ source tree CVS-aware
- renamed the package from SSLeay to OpenSSL (the files still contain
their history because I've copied them in the repository)
- removed obsolete files (the test scripts will be replaced
by better Test::Harness variants in the future)
