There are several bugs and missing features in gcc 4.0.0 (especially regarding TR1) that have been fixed in newer gcc releases, yet, despite switching to the 4.2.1 gcc compiler in XCode, we are unable to take full advantage of them.
I've heard that it's possible to switch to a manual install of the gcc compiler. If so, is that the recommended (or even only) way to obtain 4.2 std includes on OS X and how would one go about modifying XCode to use such an install? Is it via the GCC_VERSION setting?
When a new version of Mac OS X bundles the 4.2 libraries, then you'll be able to build applications using gcc 4.2 in Xcode that link against those libraries and deploy them, but there is a possibility that you will need to require users to upgrade to that version of the OS to get functionality or bug fixes exclusive to the 4.2 libraries.
You can always build your own static version of the 4.2 libraries and link to them, but you'll need to convince gcc not to use its own version of the headers using -nostdinc.
