postgres Windows distribution - openssl support

Dear Postgres developers

I installed the windows version of postgres database 8.4.9-1. Our use of
the postgres database is limited to this version.
The question is whether this version has support for openssl or not.
If this is not the case, is it true that it must be added by recompiling
from source with the -with-openssl flag?

The compilation flags for my distribution are:
PS C:\Program Files (x86)\PostgreSQL\8.4\bin> .\pg_config.exe --configure
--enable-thread-safety --enable-integer-datetimes --enable-nls --with-ldap
--with-ossp-uuid --with-libxml --with-libxslt
--with-krb5 --with-tcl --with-perl --with-python

Thank you!
