It looks like the author removed the bit about C77 from their post.

Although ANSI C wasn't a thing until 1989, the language had been around since 1972.

The original K&R book was published in 1978, and if you read it, you'll see C that's noticeably different from C89 or newer. 'C77' was probably just a fun bit of shorthand pjc50 used to describe old, K&R style C. Or at least C that's missing some ANSI features.

This was the very first time I ever saw anyone using the term C77. I really doubt the term was used knowingly instead of mixing up C with F77.
