I've just looked at the foreword of the C99 standard and the n1256
draft, and I couldn't find it.  Can you quote the precise wording?

<https://nvlpubs.nist.gov/nistpubs/Legacy/FIPS/fipspub160.pdf>
includes the 1989 ANSI C standard *and* the ANSI C Rationale.
Like many PDFs from that era, it's a scan from printed documents,
but it's still possible to copy-and-paste text from the PDF.
