Subject: Remove HAVE_TIME_H
X-Git-Tag: php-7.4.0alpha1~1852
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=a1b5698d4e3aa8514752b1fdc9a001952f984398;p=php

Remove HAVE_TIME_H

The `<time.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_TIME_H` symbol
defined by Autoconf in ext/pdo_sqlite/config.m4 [2] can be ommitted and
simplifed.

Additionally, since PHP didn't define `HAVE_TIME_H` prior in the
configure.ac the occurrence of this symbol in cli can be removed.
