[DGD] Compiling DGD with debug info

[Kurt Nordstrom]

Hey guys,

Trying to figure out why a kfun isn't working the way I want, and I'd like
to step through the code with gdb and see what's up.  Problem I'm getting
is that when I try to set a breakpoint, I get a "no symbol table" message.

Anybody know the easiest way to modify the Makefile so that it includes
all the good debugging info into the executable when compiled?
