Just tried this on W2K Sp3 and got the following results using
CMD.EXE as the shell:

D:\djgpp\home\pt>cat gawkbug.bat
@echo off
echo aaaaaaaaaaaaaaaaaaaaaaa > out.txt
gawk -f bbbb >> out.txt
echo -----------------------
type out.txt
echo -----------------------
gawk --version | head -3


D:\djgpp\home\pt>gawkbug
-----------------------
aaaaaaaaaaaaaaaaaaaaaaa
bbbb
-----------------------
GNU Awk 3.1.1

This seems OK to me.  So there's a problem with the NT4 shell
redirections, not gawk, AFAICS.  Perhaps the DJGPP command line
processing code doesn't work correctly with NT4 SP6's cmd.exe that
you are running.  Is is the original SP6 or SP6a?  ISTR that there
were some problems with SP6 because SP6a arrived pretty soon after
SP6.

BTW I also tried it under W2K SP3's command.com and it works fine
there too.  Sorry I don't have NT4 SP6 access to try it there.
