gtk1.2 also seems to be noisy; at least two of my packages (libstroke,
mtrack) pick up a ton of apparently unneeded deps from gtk-config;
[8:48am] hamish@noddy:ham/mtrack/mtrack-0.3> pkg-config gtk --libs
-rdynamic -L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -lgmodule -lglib -ldl -lXi -lXext -lX11 -lm
The pkg-config results are the same:
[8:48am] hamish@noddy:ham/mtrack/mtrack-0.3> gtk-config --libs
-L/usr/lib -L/usr/X11R6/lib -lgtk -lgdk -rdynamic -lgmodule -lglib -ldl -lXi -lXext -lX11 -lm
checklib reports that libdl, libXi, libXext and libX11 all become
unnecessary dependencies of the mtrack package as a result.
