The tex.web sources speak of a Pascal compiler
"that was available to the author in 1982."
(Yes, there are systems that compile WEB (Pascal) to C.)
This seems to have been an intention:
"a conscious effort has been made here to avoid using several idiosyncratic
features of standard \PASCAL\ itself, so that most of the code can be
translated mechanically into other high-level languages."

There is an Ada 83 WEB version.
