I have followed the discussion of redirecting stderr with some interest.
In order to compile from within my editor, it would be useful to redirect
the GCC error messages to a file. I have tried to do this using the "2R1"
feature of the GO32 environmental variable. For example,

set GO32=2r1 driver c:/djgpp/drivers/tr8900.grn gw 1024 gh 768 nc 256

Unfortunately, it does not always work on my system! Warning messages appear
to get written into a temporary file (rather than to the stdout), which
causes compilation to cease. The following example generates a warning
about redefining the constant X when "2R1" is NOT used, but compilation
progresses and the A.OUT executes normally.

#define X   1
#define X   2
main()
{
    printf("%d\n", X);
}

However, when "2R1" is added to the GO32 variable, the compilation halts
with the following error message on stdout:

d:/cc000084:1: parse error before `.'
d:/cc000084:12: malformatted character constant

Is there something obvious I am missing???
