Subject: [PATCH v2 23/29] grep: change internal *pcre* variable & function names to be *pcre1*
Date: Sat, 13 May 2017 23:15:03 +0000	[thread overview]
Message-ID: <20170513231509.7834-24-avarab@gmail.com> (raw)
In-Reply-To: <20170513231509.7834-1-avarab@gmail.com>

Change the internal PCRE variable & function names to have a "1"
suffix. This is for preparation for libpcre2 support, where having
non-versioned names would be confusing.

An earlier change in this series ("grep: change the internal PCRE
macro names to be PCRE1", 2017-04-07) elaborates on the motivations
behind this change.
