* Commands are no longer capped at 8 tokens
* Mark functions as static
* Add declaration of debugger( void ) in debugger.h
* Use f ( void ) instead of f ( )
The interface is a subset of gdb.
TODO:
* Put this behind flag, so it's possible to run b2 without the debugger.
Perhaps -db?
* Keep a command history and allow it to be accessed.
* Abbreviate long arguments in the backtrace, and wrap
long lines better.
* Implement more commands. I'm thinking of watch, condition, and ignore in
particular.
* Test the runtime cost. If it doesn't have any noticable penalty
when it's off, then it's safe to integrate this functionality
into the primary b2 executable.
* Write documentation.
* IDE integration. I'm hoping that I can hijack gdb support for any
editor that has built in support for gdb.
