I hit this while trying to use GNU time on my mac to get LOG=profile to work, to profile compilation times of individual compilation units. I built latest (1.9) from source and it didn't detect it (same with 1.8). With this patch it works as expected. > Is double square bracket some sort of escaping? Haven't seen it before. Yes, it's escaping needed to use brackets in autoconf/m4. Sometimes we put the escape sequence around the complete expression, sometimes we just double up like I did here. You should be able to find several occurrences through out our autoconf scripts. ------------- PR: https://git.openjdk.java.net/jdk/pull/7925
