It's the other way around. It's trying to use an old gis.h with a new
libgis.

The new libgis doesn't have G_gisinit(), only G__gisinit() (with two
underscores, and an extra argument). The new gis.h has a G_gisinit()
macro:

	#define G_gisinit(pgm) G__gisinit(GIS_H_VERSION, (pgm))

If a binary has a reference to G_gisinit() (as d.thematic.area does
above), it was compiled with the old version of gis.h.
