Before you go screaming off telling everybody how gdb sucks, why
don't you do some exploring with the setting options?  To get gdb
to automagically demangle C++ names, just type the following command:

set print demangle

*poof!*  There you are.  Figuring out how to do this is as simple as
browsing through the help commands.  Typing "help" gives you
a list of categories, one of which includes gdb settings.  Typing
"help set" gives you a list of everything in gdb you can set.  On this
list is "print" settings, so therefore you should type "help set print",
which brings up a whole large list of print options, oneof which is
"demangle".  Hell, I don't even use C++, and I figured this out within
half a day of starting to use gdb.

Now, you'll probably complain that you have to type this in every
time you run gdb.  Wrong again.  Create a file called 'gdb.ini' in
your DJGPP\BIN directory, and put in it all the commands you
want to be run automatically when gdb starts up.  You can even
have separate gdb.ini files in each project directory which are
loaded in addition to the main one in DJGPP\BIN.

Note to Eli, DJ, and whoever... the gdb docs don't mention 'gdb.ini'
specifically; they don't appear to have been translated at all from
the Unix versions.  Is it desirable to edit the docs, or is this a FAQ?
