Summary of travis build results

[Boruch Baum <boruch_baum@xxxxxxx>]

According to travis, the project builds fine under all recent versions
of emacs under linux. Under mac osx 10.1, it seems that one can build
emacs-w3m only in emacs 26, and only by using w3m-hack. That will
probably also hold true for emacs 27, once I learn how to pass the
correct parameters to brew (eg. --HEAD, not --devel).

The project might be usable under xemacs in linux; maybe not. The 'make'
process fails at its very end, when producing its Japanese language info
file, so the executable may be okay and usable. Unfortunately, although
'make' reports and error code '2', travis receives and exit code '0', so
reports that the build succeeded, and never proceeds to the back-up plan
of building with w3m-hack.

Travis hasn't yet really attempted to build xemacs or aquamacs under
osx. The xemacs build doesn't seem to have brew support, so travis will
need a script to manually download and build the sources. The current
script for the aquamacs build has a shell script error.

Below are details, including links to the logs.
