[openssl.org #1088] bug: SSL_load_client_CA_file always leaves errors in the error queue
After battling for a while why one could not configure more than one SSL
port in Squid when requesting client certificates it was found the culpit
is SSL_load_client_CA_file() which always leaves an error in the error
queue even if successful. This queued error then causes problems when
trying to load the certificate for the next SSL port etc..
