I made some new tests:

Test with DJGPP version 2.03 with GNU bash, version 2.05b.0(1)

Last lines of history to show what I did:

  536  djtar -x -p -o gdb-6.8.50.20090909/djunpack.bat gdb.tar >
djunpack.bat
  537  ls -alt

  539  cd build
  540  dir
  541  rm -Rf *
  542  cd ..
  543  djunpack gdb.tar 
  544  djunpack.bat gdb.tar 
  545  cmd djunpack.bat gdb.tar 
  546  cmd /c djunpack.bat gdb.tar

  Maybe there is some environment corruption somewhere...

Trying to run configure directly in source works
for both DJGPP 2.03 (tested on 20090908 tarball)
and 2.04 (tested on 20090909 tarball).
