Problems with OBJDIR != SRCDIR

[Daniel Egger <degger fhm edu>]

Hija,

I just wanted to compile Gtk+ (head) again and stumbled over a small
dependency problem:

/opt/gcc/bin/gcc -DHAVE_CONFIG_H -I. -I../../../gtk+/gdk/x11 -I../..
-DG_LOG_DOMAIN=\"Gdk\" -DINSIDE_GDK_X11 -I../../../gtk+
-I../../../gtk+/gdk -I../../gdk -DG_ENABLE_DEBUG -D_REENTRANT
-I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include
-I/usr/include/pango-1.0 -I/usr/include/freetype2 -O2 -pg -g -Wall -c
../../../gtk+/gdk/x11/gdkcolor-x11.c -MT gdkcolor-x11.lo -MD -MP -MF
.deps/gdkcolor-x11.TPlo -o gdkcolor-x11.o
In file included from ../../../gtk+/gdk/x11/gdkdisplay-x11.h:33,
                 from ../../../gtk+/gdk/x11/gdkprivate-x11.h:38,
                 from ../../../gtk+/gdk/x11/gdkx.h:75,
                 from ../../../gtk+/gdk/x11/gdkcolor-x11.c:31:
../../../gtk+/gdk/gdk.h:35:30: gdk/gdkenumtypes.h: No such file or
directory
../../../gtk+/gdk/x11/gdkcolor-x11.c: In function `gdkx_colormap_get':
../../../gtk+/gdk/x11/gdkcolor-x11.c:1131: warning: `colormap' might be
used uninitialized in this function


For some reason gdk/gdkenumtypes.h hadn't been built in the OBJDIR
and thus the compilation failed. 'Make'ing it from hand did the job
though so it seems that there needs to be some hard dependency in the
Makefiles somewhere but this is for sure not one of my expertareas so
I couldn't figure out where to do it cleanly.

Ideas?
