Apple has made a number of changes to the system header files on OS X 10.7 that can cause builds to fail. These changes only effect builds made on OS X 10.7 using the 10.7 SDK (ac_add_options --with-macos-sdk=/Developer/SDKs/MacOSX10.7.sdk). A number of bugs have been opened on these problems. I've opened this bug to help keep track of them.

These changes break builds (made on OS X 10.7) that either use the 10.7 SDK or that don't specify any SDK (which makes them use 10.7's own system files).
Are there any outstanding issues here? All the dependent bugs are marked FIXED.
> Are there any outstanding issues here? No, but there are still a couple of problems with building on OS X 10.7 (not having to do with the 10.7 SDK) that haven't yet been fully resolved. I opened bug 673541 to cover them and this bug.
