[tex-k] Issues with CTANGLE

[Andreas Scherer]

Hi Doug,

and CWEBbin replaces them with modern C:
github.com/ascherer/cwebbin/blob/master/ctang-ansi.ch#L23

Please don't expect that pre-C89 stuff will ever be corrected in the
upstream CWEB sources.  It took DEK almost a decade to even consider
'prototypes' a real thing (in MMIX). ;o)

Best,
Andreas
