The whole reason the 'redir' utility exists for DJGPP is that standard
COMMAND.COM is incapable of redirecting stderr.  It's just another
wonderful Microsoft "innovation"...  Unless you want to bundle 'redir'
with your programs, the only solution for redirection is to use a
smarter shell, such as 4DOS.

As I understand it, Unix-style core files are actually complete dumps of
the program's memory space at the time of the error.  Unix debuggers are
capable of reading this corefile and jumping directly to the point in
the program where the crash occurred.  At least, I know that gdb has
this capability on the one Unix box I used it on.  Try typing "gdb
myprog core" or something similar (I may have the syntax wrong - it's
been a while).
