Sorry, but I do not know anything about all this. The bison authors use
texinfo 4.0b to make the info docs and I was not able to create a modified
version using DJGPP stock texinfo 4.0. I have looked for texinfo 4.0b
but I have only found texinfo 4.0d and tried to compile it out-of-the-box.
I have used gcc302, bash204, bnu2112 and CVS libc (timestamp 2001-11-08).

As long as I try to create an info file from fresh extracted bison.texinfo 
everything
works ok (bison.texinfo with UNIX-style EOL). As soon as I patch the file
using stock DJGPP patch binary I get a file with DOS-style EOL. Now the
compilation fails with this output:

  cd . \
    && E:/DJGPP-2.04/BIN/sh.exe ../config/missing --run makeinfo   \
         `echo bison.texinfo | sed 's,.*/,,'`
  bison.texinfo:32: Unknown index `fn' and/or `cp' in @synindex.
  bison.texinfo:33: Unknown index `vr' and/or `cp' in @synindex.
  bison.texinfo:34: Unknown index `tp' and/or `cp' in @synindex.
  ./bison.texinfo:5461: Cross reference to nonexistent node `Decl Summary'.
  ./bison.texinfo:5434: Cross reference to nonexistent node `Decl Summary'.
  ./bison.texinfo:2427: Cross reference to nonexistent node `Type Decl'.
  ./bison.texinfo:1190: Cross reference to nonexistent node `Grammar Layout'.
  makeinfo: Removing output file `e:/project/bison-1.30e/doc/bison.info' due to 
errors; use --force to preserve.
  make.exe: *** [bison.info] Error 1

As soon as I run dtou.exe on the patched bison.texinfo, makeinfo works ok again.
I was only interested in the info docs so I have not looked very deeply into
makeinfo.c to see what the reason  for this behaviour is.
In makeinfo.c I have found  char *find_and_load (filename) and this
function opens the file in binary mode.

I did not know this.
