From: Paul Smith <psmith@gnu.org>
Date: Sun, 19 Nov 2017 13:49:26 -0500
Subject: Rework directory structure to use GNU-recommended "src" directory.

Move the source code (other than glob) into the "src" subdirectory.
Update all scripting and recommendations to support this change.

* *.c, *.h, w32/*: Move to src/
* configure.ac, Makefile.am, maintMakefile: Locate new source files.
* Basic.mk.template, mk/*: Update for new source file locations.
* NEWS, README.DOS.template: Update for new locations.
* build.template, build_w32.bat, builddos.bat: Ditto.
* po/POTFILES.in: Ditto
* tests/run_make_tests.pl, tests/scripts/features/load*: Ditto.
* make.1: Move to doc.
* mk/VMS.mk: Add support for building on VMS (hopefully).
* makefile.vms, prepare_w32.bat: Remove.
* SCOPTIONS: Update to define HAVE_CONFIG_H
