This is, I would say, a problem with your gcc configuration. GLIB
includes both the float.h and limits.h header files, and apparently
one is coming from gcc and the other from your system header files
and they are conflicting.

OK, I think I know which problem this is. It is a segfault that
is occuring in the XIM code. You can work around it for now
by compiling GTK with --disable-xim; I'm working on a fix now.

Hmmm. Are you compiling with a separate builddir and srcdir? If
so, you should run testgtk with 'make test'. Otherwise, it won't
find the necessary pixmaps.

This is something I see. (The problem is that DND bypasses the
GTK layer, so it ignores the modal grab, and another drag can
occur while not expected. It should be pretty easy to prevent
this in testgtk.c, though the problem really deeper.

This is the same problem as the DND thing.

This is the same srcdir != builddir problem.

Same XIM problem.

Thanks for the report,
