Fix tricky issue: basic tools must be compiled with -mt as well,
otherwise they won't be able to use plugins (and for instance, kde needs
uic plugins for its widgets)
Most notable improvement seems to be font-handling, especially unicode stuff.
Configured to relocate plugins at a reasonable place. Includes *sql
plugins, though they are thoroughly untested at the moment.
Works good enough to recompile xglobe for instance. Still work to do
though, some paths are probably incorrect yet.
