That's really unfortunate. Comments in code are useful but they are
no substitute for properly written internals documentation.
By contrast, the internals documentation of GCC seems to be pretty
helpful and reasonably up to date.
Given a program as complex and inscrutable as GDB, if the best you can
tell newcomers is "use the source, Luke", you're going to turn off a
lot of them. Only those who are extremely motivated will make
progress against such a barrier.
For example: Bug #186 has been troubling us on and off for a long
time. I would like to fix it. But given that this involves going off
into the deep jungle of the GDB symbol and type machinery, and the
fact that there is no useable documentation for this stuff, I haven't
been able to do this.
