Trying to load DEM data on a PowerPC Mac in viking 1.4.1 fails with:
** (viking:13232): WARNING **: unzip_hgt_file(): wrong format
The attached patch brings endian awareness to unzip_hgt_file()
Thank you very much for noticing the problem and providing the fix.
This has been applied to the master code base and will be included in the next main release (probably 1.5).
