OK, so as we have to investigate issue reported by Tom error anyway, we might try to fix this as well.

Unfortunately, it seems like internal inconsistency of gtk2 dev libraries (AFAIK, I do not even use GTimeVal anywhere). Unfortunately, this error does not happend on any of distros I have available, so it is a bit hard for me to fix, but I guess we should fix it by specifying max gtk2 version somehow, e.g. -DGLIB_VERSION_MAX_ALLOWED=GLIB_VERSION_2_60 in compiler flags or perhaps even before gtk/glib include (that is prefered IMO) or by -Wno-deprecated-warnings in compiler flags.
