Building ddd

I've built ddd from ddd-3.3.9.tar.gz, and had a couple of problems. I 
had to add "#include <stdio.h>" in stdclass.C.  And for execution had to 
"cp -r vsllib ddd" while in directory ddd-3.3.9. This appears to have 
some of the same problems as the gentoo build, but at least it only took 
one <cntrl-c> to track down one bug in my code.  The hour glass is 
always visible when the mouse in the the source file however.  My CPU 
monitor does not indicate any cost associated with this.  I could also 
note that the configure needed the option  
"--enable-builtin-app-defaults" for successful execution.
