FreeBSD. This method attempts to centralize all the necessary hacks or work arounds in one of two places in the tree (src/Makefile.inc1 and src/tools/build). We build a small compatibility library (libbuild.a) as well as selectively installing necessary include files. We then include this directory when building host binaries. This removes all the past release compatibilty hacks from various places in the tree. We still build on tip of stable and current. I will work with those that want to support more, although I anticipate it will just work. Many thanks to ru@, obrien@ and jhb@ for providing valuable input at various stage of implementation, as well as for working together to positively effect a change for the better.
