[Delta] QCA2 build problems under win32-msvc2008/Qt4.4

[optimism_]

Hi,

I'm struggling to build a copy of QCA2 with the openssl plugin under
the latest version of visual studio, and the Qt 4.4 pre-release code.

I've got a successful build working under linux so far, but the
windows one is causing me trouble. Following the instructions in the
respective INSTALL files, I've got both qca-2.0.0 and
qca-ossl-2.0.0-beta3 build successfully producing qcatool2 and the
qca-ossl2.dll files. I've moved them to the Qt directory.

qcatool shows no available providers, despite showing the correct search paths.

I've single-stepped through the QPluginLoader source, and its bailing
out while trying to find the qt_plugin_query_verification_data symbol
and concludes the ossl dll is not a valid Qt plugin.

Is this a known issue or bug with QCA? Is building it in this way
supported at all, or am I trying to do something that just isn't
possible?

Any response would be greatly appreciated; if QCA can't be made to
work I'll need to find an alternative asap.
