I'd suggest removing the K&R requirement (hopefully the SC will consider
this again after 3.3) and making libbanshee required before merging this
feature to mainline.  The existence of optimizations in some copies of a
given GCC version but not others is likely to yield confusion with bug
reports some people can reproduce but not others on the same platform
(which then get wrongly closed).  It's a good principle that a given
version of GCC should produce identical output for given input code and
options, whatever the host system (at least provided sufficiently recent
GNU binutils is installed).

(Your question is still relevant for people trying the branch for now,
although I don't know if any such people are using K&R systems.)
