I'd like to see geotiff-support as well. I've used it in xastir running 
in cygwin and it works fine. The geotiff-packages are available in 
compiled form via the cygwin installer (libgeotiff*).

Oh yeah, someone could also remove those

"Warning: no PCS in geotiff file mymap.tif, assuming map is in lat/lon!"

warnings from stdout/stderr when using unprojected geotiffs that are in 
WGS-84. Or is there a better way to get rid of this error?
