0.28-pre14  28 Mar 2004
     distcc integration:
     * added demo-cluster.sh to demonstrate how to set up a hetrogenous
       compile cluster where all nodes just mount the same directory to
       get the compilers
     * renamed mkdistlinks.sh to mkdistcclinks.sh, renamed mkdist.sh to clean.sh
     * mkdistcclinks.sh no longer indents the #!/bin/sh in the scripts it generates,
       properly deals with the .exe (or lack thereof) on files in bin,
       and interfaces properly with cygrunsrv and distcc-stringmap.patch
     * patches/distcc-2.13/distcc-stringmap.patch extends distcc to
       better handle installations where compilers differ only by
       the name of the directory they're installed in.

demo-cluster.sh creates /opt/distcrosstool, which is just like /opt/crosstool
except for an extra level of hierarchy named for the *build* machine.
(This is useful if you have a bunch of workstations of different
OS's or CPU types all mounting the same remote filesystem.)

Here's how I tested it:

On a Cygwin box, I ran
  demo-cluster.sh
  /opt/distcrosstool/i686-pc-cygwin/common/bin/run-distccd.sh
and on the Linux box, I did
  sh demo-cluster.sh
  DISTCC_HOSTS=192.168.1.44   (the IP adr of the Cygwin box)
  export DISTCC_HOSTS
  /opt/distcrosstool/i686-pc-linux-gnu/i686-unknown-linux-gnu/gcc-2.95.3-glibc-2.1.3/distributed/bin/i686-unknown-linux-gnu-gcc -c hello.c
(where hello.c already existed).
And sure enough, it sent the job over to the Cygwin box, which happily
compiled it.

Still needs documentation and some shaking down, but at least the
out-of-the-box hetrogenous compile cluster demo is starting to work!
