So this is the big problem: I wonder why couldn't it open that?

Did you set TMPDIR on the machine running the server?  If so, why is
it seeing \tmp not /tmp?  Does the \tmp\distccd_ce7f0d4c.i file exist
on the server?  Try running with DISTCC_SAVE_TEMPS=1: do the contents
look reasonable?

Thanks for the trace; that helps.  A trace from the server might help
too.

This is ok.  8 is the length of the second argument.  (See
protocol-1.txt if you care.)

No, this is OK, just a confusing trace message.

No, the first one was just preprocessing (cpp).
