[Bug bootstrap/29482] New: libcpp/configure - no usable dependency style found

Dependency creation fails for libcpp on OpenUnix 8.5.
Surprisingly enough the previous phases of the gcc bootstrap work well enough
and also seemed to do some dependency work.

The cc on Caldera OpenUnix 8.5 can generate dependencies but it's not used for
this purpose. Here is the man : 
         Causes the pathnames of all files included to be printed, one
         per line, on the standard error output.

I'm not a shell wizzard but I guess something like the following should be
added to depcomp (I mean - the following does NOT work :) ). 
  cc -c -H "$object" 2>"$tmpdepfile"
        cat $tmpdepfile
  if test $stat -eq 0; then :
    rm -f "$tmpdepfile"
    exit $stat
  mv "$tmpdepfile" "$depfile"

I know the stderr may not available for the purpose.
May be someone more familiar with these scripts can do the trick?

Thank you,

P.S.1 Here's the uname -a : OpenUNIX T114p 5 8.0.0 i386 x86at Caldera UNIX_SVR5

P.S.2 May be mp4 could be made to generate these dependencies so this whole
script collection becomes unneeded?
