Hmm...

I am confused now.
Do I not understand how -pthread and -shared should work together ?
Does -pthread work only on final executables ?
Also, if GVim loads libgnomevfs-2.so.0 via dlopen() and is not linked
with it in a regular way, should GVim still be linked with all the
dependencies of libgnomevfs-2 (including some threading lib) ?
$ pkg-config --libs gnome-vfs-2.0
-pthread -L/usr/local/lib -L/usr/X11R6/lib -lgnomevfs-2 -lbonobo-2
-lgconf-2 -lgobject-2.0 -lbonobo-activation -lORBit-2 -lm -lgmodule-2.0
-lgthread-2.0 -lglib-2.0 -liconv
What's the point of dlopen() then if you are supposed to know certain
sub-dependencies in advance ?
