I will probably add windowing in the next (???) release of ladybug, but 
currently you can't do that.

Ladybug failed to dereference the environment pointer (go32 version 1.1x 
doesn't pass the environment to the debugger, so ladybug has to "borrow"
the debuggee's environtment.) and stat () failed under DPMI (it 
called getenv() to find TIMEZONE, and crashed.) That's why there is no 
dpmi version of the debugger in the release. I'm currently working on 
getting the debugger to be DPMI compatible. The 0xe... references and 
stat () crashes have been solved, but the problem of getting the 
environment remains.

  The ought to be unzipped into the parrent dir only to rebuild go32, but 
the problem is go32's sources changed with the maintanace releases...

It seems like gcc tried to use the NPU that your machine doesn't have. 
You might try to use the emulation package (emu387???) to fix that problem.
I have no problem rebuilding ladybug.

  I rebuilt ladybug (and ladydpmi) on my 386SX16, 4MB, and 11M of free HD 
space. The rebuild went fine (except that it's "quite" slow (It took me 
almost 20 mins to rebuild the whole thing.) :-<
