[Psi-Devel] debugging on windows

[Norman Rasmussen]

I think mixing runtimes is okay, so long as you create and dispose objects
using the same runtime.  Once I had rebuilt Qt+QCA+Psi with the new runtime
everything was fine.  Obviously Qt takes some liberties with where objects
are created/disposed when it comes to plugins.  The openssl libs didn't need
to be updated (I re-linked the existing object files with the new runtime in
the end to keep things complete in the end).

My new 4.3.4 Qt libs (+qca), are now built with vc9, and my nightly builds
will all be vc9 going forwards. Also going forwards I will not be uploading
the pdb file with the exe.  It will be stored on the build machine and
rotated with the rest of the files, but I don't see any point in uploading
it to the released files.  People are more than welcome to request the files
from me if they want them.
