Component:  Raster                 |    Version:  svn-releasebranch76

 This is a case of a (hard to trace) buggy behavior when linking an
 external raster map of type Float32. Here an external report:

 In short, a raster map of type Float32, linked to an EPSG:3035 Location,
 via`r.external`, delivers different descriptive statistics under Windows
 than what the identical workflow does under Linux (and what gdalinfo tells
 about the data, both under Windows and Linux).

 Also, the `--overwrite` flag given to either `r.external` or `r.in.gdal`
 does not seem to work under Windows.

 Perhaps all these are known issues?
 Perhaps this case has to do with the presence of NULL cells too? As is the
 case of the example map I use.

 The example map `input_water_resources` is available at
