--- Comment #1 from Ryan Schmidt wine-2011@ryandesign.com 2011-04-19 03:30:30 CDT --- I'm going to guess commit 5015f388 is what caused this, since that's the commit in which the use of SSLCopyPeerCertificates was introduced, and I'll guess SSLCopyPeerCertificates is not available on Mac OS X 10.4. The commit message is "secur32: Add alternative schannel implementation for Mac OS X. It uses the native Secure Transport API rather than GnuTLS." I am configuring with --with-gnutls and gnutls is installed. But this alternative implementation seems to be getting used anyway, even when it won't work. Is there a way to tell wine I don't want this alternative implementation and to let it use gnutls as it did before? Anyway, ./configure --help lists the option --without-gnutls, which implies that --with-gnutls is the default, but that doesn't seem to be the case here anymore.
