[distcc] distccd paths

[jason.davis at acterna.com]

Our build environment contains multiple compilers with the same name,
installed in different directories.  Only one of these compilers is used by
a particular developer at a time (so doing the client side of distcc would
seem to work using masquerading), but how does distccd know which compiler
to use?  Is the entire path to the compiler passed to the server, or does
it use PATH and/or DISTCCD_PATH to look for the appropriate executable?

Thanks for the help.
