 Source distributions downloaded from one of the GNU FTP sites need

-unzip the package.  That's because some file names in the official

-need first to retrieve that file, and then invoke `djtar' to unpack

- djtar -x -n lst gdb-5.0.tar.gz

+(The name of the distribution archive and the leading directory of the
+path to `djunpack.bat' in the distribution will be different for
+versions of GDB other than 5.0.)
+
+If the argument to `djunpack.bat' include leading directories, it MUST
+be given with the DOS-style backslashes; Unix-style forward slashes
+will NOT work.
+
+If the distribution comes as a .tar.bz2 archive, you need to unpack it
+as follows:
+
+ bnzip2 gdb-5.0.tar.bz2
+ djtar -x -p -o gdb-5.0/djunpack.bat gdb-5.0.tar > djunpack.bat
+ djunpack gdb-5.0.tar
