The rule about conversions from arrays to pointers is different in C99

"an expression that has type ``array of type'' ...".

The change from "lvalue" to "expression" was made in C99.  I wonder why
that was done.

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?

BTW, you have a copy of ANSI C89?  Hard or soft copy?  Do you know if
it's still available in some form?

as ANSI X3.159-1989 Programming Language - C.

<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.
