Bug fix:  In |hexl_decode|:  This caused a problem with |Handle_Value_Type::data|.

Fixed `make' rules:  Removed redundant`-g' option.  Also, removed it and the optimization option
from the link commands.  They are compiler options, so not used for linking.

Now compiling with `-O1' instead of `-O2'.  Compiling without any optimization causes an error
involving the GnuTLS library, so it would probably not be easy to find out what's causing it.
