Subject: Remove HAVE_STDIO_H
X-Git-Tag: php-7.4.0alpha1~1907

Remove HAVE_STDIO_H

The `<stdio.h>` header file is part of the standard C89 headers [1]
and on current systems can be included unconditionally.

Since PHP requires at least C89 or greater, the `HAVE_STDIO_H` symbol
defined by Autoconf [2] can be ommitted and simplifed.
