This fix is not yet in. Here are diffs for

This patch fixes filebuf test failure introduced by earlier patch for
std_fstream.h to fix DOS style (CR LF) file handling on output. Test
fails later anyway as it expects only LF to be written to file when LF
if sent to filebuf.
  
I'm sending this also to djgpp-workers as patch could be usefull to
somebody else
