[Qgis-developer] EPSG codes

[Trevor Wiens]

I did check the code for crssync and it appears that only the gdal csv and
wkt files are what is checked. This makes the situation on my machines
confusing as the reference to ESPG:6148 is absent from the gdal 1.9 and yet
it is present in the srs.db on the same machine. How it got there is
baffling, but this would appear to be a distribution issue.
