[tex-k] [CWEB] Cleanup release 3.64ae

[Andreas Scherer]

Dear all,

a few days ago, DEK released 'CWEB 3.64ae' and directed support questions to 
your address. Following is a list of issues I'd like to see addressed:

* Do not pack backup files, ctangled sources, and executables in the archive;
  this concerns the 'examples/' subdirectory.

* The expanded 'ctangle.c' somehow doesn't match its origin 'ctangle.w';
  it uses '<stdlib.h>' instead of predeclaring 'string' functions and it is
  unclear, where this (manual?) change comes from.

* 'wordtest.w' should define 'PHICLONE' as 'unsigned' by appending a 'u'
  to the numeric value to avoid a compiler warning.

A multi-decade project to improve and extend CWEB can be found at 
https://github.com/ascherer/cwebbin – it contains far too many details to list 
here, but at least on Linux (both RPM and DEB) it makes use of the unmodified 
source drop 'cweb-3.64ae.tar.gz' and applies its stuff on top.

Cheers,
Andreas Scherer
