What C and C++ flags do you use for builds? Can you check if these warnings are present if you build MySQL 5.5.24 with the same flags on the same system? For the Percona Server-specific warnings, please submit a new bug report. For the warnings shared with MySQL please submit a bug report to bugs.mysql.com (after checking if it's already been reported). Thank you.
