Subject: [PATCH] regex.3: Remove unnecessary include
Date: Sat, 10 Oct 2020 19:50:02 +0200	[thread overview]
Message-ID: <20201010175001.3818-1-colomar.6.4.3@gmail.com> (raw)

POSIX requires that the <regex.h> header shall define
the structures and symbolic constants used by the
regcomp(),  regexec(), regerror(), and regfree() functions.

Therefore, there should be no need to include <sys/types.h> at all.

The POSIX docs don't use that include:
