"flexible"?!
gdb is a great debugger, but to say that the macro system is lacking is to make 
a gross understatement.

e.g., http://article.gmane.org/gmane.comp.gdb.general/445:

the following:

define break_foo_bar
  break foo
  commands
    print x
  end
  break bar
  commands
    print y
  end
end

does not work because, apparently, the first "end" closes both
"commands" and "define" and there is no file loaded at this time, so I
get this error:
.gdbinit:97: Error in sourced command file:
No symbol table is loaded.  Use the "file" command.

Is there a way around this problem?
