As Lorenzo notes, the suffixes suggest that the directory names should use "cpp", too, but there is a difference. In "cxx11", the "cxx" is in reference to a standard version, rather than to the language itself, so a distinction might be appropriate.

I, too, don't really have a preference. However, the directories and corresponding macros should use p/P or x/X consistently.
