I would much prefer using sed over perl here, as sed is a POSIX tool and the previous Autotools variants of the compiler wrappers were already using sed. If that's agreeable, I will fix this by either detecting the correct flag in CMake at configure time or adding a fallback to using "-r" in the compiler wrappers scripts when the "-E" option isn't supported.

Agree - we should be moving away from Perl, over time.
