Subject: [PATCH 2/4] configure.ac: Use AC_LINK_IFELSE for -gz=none check
|
||
|
|
|
||
|
|
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.
