[distcc] precompiled headers and g++ -E

It appears that the -E option of g++ prevents use of precompiled headers
(pch).  The result is a preprocessed file, but correct .h.gch files are
not pulled in.  This is a problem when g++ and pch are used by distcc.
Before distcc sends a job to a remote machine, it preprocesses it on the
local machine by running g++ -E...  This has the effect of not using
.h.gch files which in turn makes the remote compilations take much more
time.

Is there a way to tell g++ to use precompiled headers even if the -E
options is specified?
