          Issue ID: 23249
           Summary: Deprecation: argument &p for format specification "%m"
                    must be char*, not char**
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody at puremagic.com
          Reporter: ibuclaw at gdcproject.org

This deprecation message is wrong, the %m specifier needs to accept a `char**`
as it must dynamically allocate it.

On an implementation note, it's also not a GNU, but a POSIX.1-2008 extension.
