Subject: [COMMITTED] configure.ac: Use AC_LINK_IFELSE for -gz=none check
Date: Fri, 27 Jan 2023 15:26:26 +0100 [thread overview]
Message-ID: <20230127142626.14725-1-mark@klomp.org> (raw)
Because of a bug in gcc 13.0 (pre-release) -gz=none does not work
correctly when linking the final binary in some situations (when
-gz=zstd isn't supported). Work around this by explicitly checking for
support with AC_LINK_IFELSE.
