Could it be that some are in the -o directory, and some are in the
source directory?

I just realized that the behaviour will be inconsistent between local
and remote compilations.

Does it work if you use -MD -MF?  As far as I can see explicitly
giving the dependency file with -MF ought to always work.

Do you mean it works with CC='distcc gcc' but not with CC='distcc'?
How strange.  I'd appreciate a logfile for that.

Is it possible that 'cc' is a different version to 'gcc'?
