According to https://github.com/openjdk/jdk/pull/17986#issuecomment-1975396416, [JDK-8326583](https://bugs.openjdk.org/browse/JDK-8326583) broke ccache compilation.
The reason was that the ccache command line included `CCACHE_SLOPPINESS=pch_defines,time_macros`, and the comma was expanded wrongly, causing `time_macros ...` to look as an additional argument to `SetIfEmpty`. ------------- Commit messages: - 8328079: JDK-8326583 broke ccache compilation Changes: https://git.openjdk.org/jdk/pull/18273/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=18273&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8328079 Stats: 24 lines in 1 file changed: 0 ins; 0 del; 24 mod Patch: https://git.openjdk.org/jdk/pull/18273.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/18273/head:pull/18273 PR: https://git.openjdk.org/jdk/pull/18273
