I tried to compile both versions: default (with GNOME) and with
--disable-gnome. In gnome version all three tests works ok.

Hm, if such parts are my #ifdef BUILD_WITH_GNOME than I don't think so.
I saw very carefully and tracked includes and sources recursively on
occurence of gconf, bonobo and libgnomeui things. Some very innocent
looked widgets were exposed in GNOME complicity on close look :)

Ah, I remember autotools give message about 'Variable CLEANFILES must be
initialized before +=' or something similar.

Also note about new libgnomedb/gnome-db-i18n.h file which is slightly
modified bonobo/bonobo-i18n.h. May be we should modify libgda/gda-intl.h
in a manner like gnome-db-i18n.h and move it to libgda_INCLUDES so
gnome-db-i18n will not be needed.
