[distcc] A question regarding pump mode

[Tian Fang]

Hi,

Come cross this wonderful tool, distcc with the pump mode. Have a
quick question on the implementation of the pump mode.

My understanding of one purpose of include server is to find out the
include files for each source code to be distributed. include server
implements its own parser to preprocess the source files to get the
list of files. Wondering why not using the -M opt provided by the
compiler instead of writing the new parser. Appreciate someone could
share some reason behind this design.
