Hi folks.

I'm using the Intek C++ compiler on a 386 PC running DOS 4.0.

This compiler outputs its  error messages to stderr,  so I cannot  use
the redirection character ">" at the command level  to save the output
in a file.

Does anyone have a  hack that will  modify DOS to  overlap stderr onto
stdout?

I  tried writing a   short assembly program   that uses  DOS  INT 21H,
function 46H (CDUP) to force stderr to output to stdout, but it didn't
work.   I'm not  very knowledgable  with  the DOS interrupts,  so   my
understanding of CDUP's operation may be wrong.

I  also  retrieved REDIRECT.C from Simtel20,   but it didn't  solve my
problem.   In fact it  causes a  stack   overflow error.  Part of  the
problem might stem from the compiler  switching the 386 into protected
mode to take advantage of  extended  memory and then switching back to
real mode when it's done.

Thanks in advance for any help.
