new depcomp causes trouble w/fileutils

[Jim Meyering]

Hi Tom,

I use the gcc snapshot of the day (checked out 2001-01-11.04h59 UTC)
and tried putting your latest depcomp into fileutils.  It worked fine
for builds in a directory that was already configured (stale depmode?),
but when I ran `make distcheck', it ended up running in gcc3 mode and
failed because it put preprocessor output in the .o file.

The symptom was that linking failed because the .o file wasn't valid.

Here's s tiny test case that tries to demonstrate what happened:

  $ cat k.c
  int foo () {}
  $ DEPENDENCIES_OUTPUT=1 gcc -c -o k.o k.c -M -MT k.o -MF k.Po
  $ cat k.o
  # 1 "k.c"
  int foo () {}

I'm using automake-1.4b.
