# what's up with the following tests ?
# I downloaded, built and installed the lzma-4.32.7 source package directly 
# from http://tukaani.org/lzma/download and they resulting library doesn't have 
# these symbols. Also "grep -R auto_decoder *"  gives no results.
# Where should they come frome ? Alex
