Lots of bugfixes and portability improvements were
made. The "--scan-includes" option was added to
distcc. This shows which headers distcc would send
to the remote machine in pump mode, without
actually compiling anything. This provides a
simple interface to the include server. The
"--disable-Werror" option was added to configure.
This disables the use of gcc's -Werror option when
building distcc, allowing compilation of distcc to
succeed even if gcc issues warnings.
