BSD and darwin gcc standard libraries aren't always detected.

[Daniel James]

If you look at some of the config results for NetBSD and Darwin they gcc stdlib hasn't been detected (it says 'Unknown ISO standard library') because including <cstddef> doesn't define the C++ macros.

The attached patch fixes this for darwin 4.0.1 and hopefully the other platforms as well.

[John Maddock]

Sigh... looks like someone broke this in ​https://svn.boost.org/trac/boost/changeset/52104, can you go please ahead and commit, and check the release branch as well?

Thanks, John.

[John Maddock]

Looks like it's broken for Borland as well as all the glibc platforms, I'm CC'ing Dave Deakins as well since he caused the breakage :-)

John.

(In [52246]) Include <utility> for some versions of gcc's library.

Sometimes gcc's <cstddef> doesn't define the C++ macros, so check for it and include <utility> in that case. Also remove a workaround from container_fwd.hpp

Fixes #2924.

[Daniel James]

Sorry, I only read your comment after committing. Reopening for Borland.

[Daniel James]

Oh, and this is only on trunk. The release branch is fine.

[Daniel James]

Actually, it isn't. I had an old version. I think we should revert the change on release. Especially since we're coming up to the deadline.

[John Maddock]

Nod, I agree. If David can fix the regressions on Trunk we can always merge to release branch for the next release.

John.

[David Deakins]

(In [52254]) Reverted change in boost/config/select_stdlib_config.hpp change in rev 52221. Some gcc and Borland stdlibs don't pick up the C++ macros needed for stdlib detection from <cstddef>. See ticket 2924.

[David Deakins]

My bad. Change reverted on the release branch. I'll look into the Borland issue on the trunk right away and see if there is an easy patch for it.

[David Deakins]

Ok, I just checked in a change to the trunk that will hopefully remove the regressions. I'll keep an eye on the Borland results and close the issue if the problem is resolved.

[David Deakins]

The trunk results have cycled and it appears that with the revised change the Borland and gcc results are correct again. I believe this issue is now closed.

[Daniel James]

(In [52324]) Merge quickbook and hash changelogs. Tweak gcc detection in container_fwd.hpp

Detect gcc stdlib for gcc 4.0.1.

For some reason the normal macros aren't defined for the standard library that comes with gcc 4.0.1 (although maybe just on BSDs?). So try to detect the library for that compiler.

Oops, sorry that got posted to this ticket. I didn't merge any changes to config there, as the later patches reverted the changes I made to config.
