[Qgis-developer] EPSG codes

I don't understand it either; I'm not in any way suggesting it makes sense.
I'm simply describing how it is.

The confusing state of my machines suggests that crssync may do other
things than just use the GDAL sources to populate srs.db. Is that mistaken?
I haven't looked at the source for crssync; do you know for certain that it
only scans the gdal csv files?

The point the original question poster made and which I verified was that
with QGIS 2.4 on Linux, EPSG:6148 was present and supported; an upgrade to
2.6.1 removes it. I don't how or why. Again, my machines suggests that this
is more than a GDAL library issue.
