Dependencies for config:

detail: boost/detail/endian.hpp

A dependency from config to detail is not a good thing because detail depends on too much.

The 'boost/detail' really isn't a library as it is just a number of individual header files none of which belong to any particular library. So thinking about what 'boost/detail' as a whole depends on does not seem worthwhile.

boost/detail/endian.hpp is now only a forwarding header to predef, so it could and probably should be moved to predef, which seems to depend on nothing.

OK.

But I was wondering what in config uses endian.hpp. Turns out the only use is in boost/detail/limits.hpp, a file that has been put into config for some reason.

I don't see where endian.hpp is being included by limits.hpp.

I can't find anything in config or in Boost that uses this file. What is its purpose?

John or Dave should know. Hopefully one of them will answer that.

boost/detail/limits.hpp was deleted on trunk in subversion because it had a non-boost license. It should probably should also be deleted from master, it used to be included from boost/limits.hpp when BOOST_NO_LIMITS is defined. The original change is at: https://github.com/boostorg/config/commit/3ce54f0e8bcb173989f9632d41e966f65d...

Is the dependency tracker public at all?
