 Just wanted to import gmted2010 data having extent to the south of 90d 0'
 0.50"S. I don't see a clean fix. One workaround is the throw away one row,
 but then half a pixel is missing to 90S.
 (see also: http://grass.osgeo.org/wiki/Global_datasets describing the same
 problem with etopo1).

 Using grass 6.4.2 r.in.gdal does the wrong thing (TM). It assumes there is
 a rounding error and adjusts the south extent to -90S and displays the
 warning:
 "WARNING: Fixing subtle input data rounding error of south boundary
          (-0.000138889>1e-06)
 "
