[Qt-interest] Help needed, I am stuck building the QPSQL database plugin on Win XP/Qt 4.5.1/mingw

[Thomas Dähling]

Also keep in mind that with dynamic linking also libpq.dll and it's
requirements must be locatable in the environment. Best is to check
the output of Dependencywalker where it complains about missing libs.
