Markus, 

Normally this could be found using the call:

  CPLGetConfigOption( "GDAL_DATA", "/usr/local/share/gdal" );

However, if you are using it to find the .csv files, this is normally
accomplished by calling CSVFilename("pcs.csv") and letting it
find the files.  

Perhaps you should submit the patches as is, since I will almost
certainly want to fiddle with some of how this is handled. 

Best regards,
