Yes it can be null:
if (!fdeps_file)
fdeps_stream = out_stream;
else if (fdeps_file[0] == '-' && fdeps_file[1] == '\0')
fdeps_stream = stdout;
else
{
fdeps_stream = fopen (fdeps_file, "w");
if (!fdeps_stream)
fatal_error (input_location, "opening dependency file %s: %m",
fdeps_file);
}
if (fdeps_stream == deps_stream && fdeps_stream != stdout)
fatal_error (input_location, "%<-MF%> and %<-fdeps-file=%> cannot share
an output file %s: %m",
fdeps_file);
Which means out_stream is also deps_stream .
