If one has to resolve to start hunting for answers in header files, all they want is for you to start hiding them in random places. grep -r <blah> /usr/include is easy. > In that respect, it is even better to relocate them to a different > location than /usr/include, since they're not *FreeBSD* headers, > they're clang internal headers. > > In other words, I consider this a win, not any form of loss. :) > > -Dimitry > They are FreeBSD headers as long as you ship clang as part of FreeBSD sources. Your change does not improve usability, since headers are internal and having them under /usr/include does not hurt anyone nor is that a change that is hard to maintain. By moving them you actively hurt source transparency by forcing someone to potentially hunt for answers in many disjoint directories and as such this is a net loss. No smilies. The choice is yours, of course. -- Alexander Kabaev
