Hamish, 

Cool, good work!  I am happy to allow portions of gdal_misc.cpp
to be relicensed under the GPL when copied into GRASS.  In
fact, I am happy to allow any amount of code from GDAL that I
hold the copyright on to be relicensed under the GPL if it would
be useful in GRASS, as long as the original copy in GDAL remains
under it's original license.

In C++ you would do a test like this to see if a driver supports
creating new datasources.  I thnk the C equivelent is to call
OGR_Dr_TestCapability(). 

        if( !poDriver->TestCapability( ODrCCreateDataSource ) )
        {
            printf( "%s driver does not support data source creation.\n",
                    pszFormat );
            exit( 1 );
        }

Ugg, this really sucks doesn't it?
