Just to mention that the gdaldem utility, that has landed into GDAL 1.7.0dev trunk, is derived from Matt Perry dem tools (derived themselves from ancient - public domain - GRASS code ;-)). You can grab it here : http://trac.osgeo.org/gdal/browser/trunk/gdal/apps/gdaldem.cpp. It should compile fine against GDAL 1.6.X.
