If the user wishes to ignore the difference between the apparent coordinate system of the source data and the current location, they may pass the -o flag to override the projection check.
If the user wishes to import the data with the full projection definition, it is possible to have r.in.gdal automatically create a new location based on the projection and extents of the file being read. This is accomplished by passing the name to be used for the new location via the location parameter. Upon completion of the command, a new location will have been created (with only a PERMANENT mapset), and the raster will have been imported with the indicated output name into the PERMANENT mapset.
The target option allows you to automatically re-project the GCPs from their own projection into another projection read from the PROJ_INFO file of the location name target.
The r.in.gdal command does support the following features, as long as the underlying format driver supports it:
Planned improvements to r.in.gdal in the future include support for reporting everything known about a dataset if the output parameter is not set.

"ERROR: Projection of dataset does not appear to match the current location."
You need to create a location whose projection matches the data you wish to import. Try using location parameter to create a new location based upon the projection information in the file. If desired, you can then re-project it to another location with r.proj. Alternatively you can override this error by using the -o flag.
"WARNING: G_set_window(): Illegal latitude for North"
Latitude/Longitude locations in GRASS can not have regions which exceed 90° North or South. Non-georeferenced imagery will have coordinates based on the images's number of pixels: 0,0 in the bottom left; cols,rows in the top right. Typically imagery will be much more than 90 pixels tall and so the GIS refuses to import it. If you are sure that the data is appropriate for your Lat/Lon location and intentd to reset the map's bounds with the r.region module directly after import you may use the -l flag to constrain the map coordinates to legal values. While the resulting bounds and resolution will likely be wrong for your map the map's data will be unaltered and safe. After resetting to known bounds with r.region you should double check them with r.info, paying special attention to the map resolution. In most cases you will want to import into the datafile's native projection, or into a simple XY location and use the Georectifaction tools (i.rectify et al.) to properly project into the target location. The -l flag should only be used if you know the projection is correct but the internal georeferencing has gotten lost, and you know the what the map's bounds and resolution should be beforehand.
