I did not build the gcc tool so I am not certain, but I believe it is
just from the standard distribution.

About debugger there are at least two full screen debuggers:

- edebug32 which came with DJGPP go32 package
- Ladybug which is a modified version of edebug32.  Ladybug has
different user's interface as Ladybug allows us to debug from an ANSI
terminall attached to a comm port.  It also has a built in performance
analyzer for you to produce a histogram of percentage of time where
the CPU spends its processing (in Protected mode).

Long Doan, who wors for us (Netrix), modified edebug32 and formed
Ladybug.  We, therefore, use Ladybug all the time.  We have the comm
port connected to our Sun or HP Apollo work station and debug from
there.  This way we can always view the source code on the same
screen.

I believe, both debuggers can display C source code if you have the C
source file loaded on the PC.  We do not use them, as the diassebled
display always give us the module/line number info which is over
ninety percent of what we need during debugging.  Downloading source
code can be a real pain if you want all the files to be up to date.

Hope this helps.
