New installed files

Backward compatibility issues

Due to the 2-digit number '10' in GDAL 1.10, the GDAL_VERSION_NUM macro has been changed. The new advised way of testing the GDAL version number (for GDAL 1.10 or later) at compilation time is :

#ifdef GDAL_COMPUTE_VERSION /* only available in GDAL 1.10 or later */ #if GDAL_VERSION_NUM >= GDAL_COMPUTE_VERSION(1,10,0) / #endif #endif

Testing of previous versions is of course unchanged.
