Hi Werner:
As our C++/Windows expert would you be willing to take a look at this patch?
For your convenience I have downloaded it and attached it to this post.
The patch is quite small (~10 changed lines), but I don't understand the C++
implications of these suggested changes to allow qt.cpp to build on MSVC 9.0
(2008) so I don't feel competent to apply this patch myself.
Alan

Summary: qt driver - proper MSVC exports
Initial Comment:
Compiling plplot with MSVC 9.0 (2008) failed due to some missing/conflicting
__declspec() specifiers.
There were also a mangled name (C++) of the plD_DEVICE_INFO_qt in qt.cpp.
See attached patch.
