<p>Clang 3.1 adds support for anonymous structs and anonymous unions, added in
|

the latest ISO C standard. Use <code>-std=c11</code> or <code>-std=gnu11</code>
|
||||
to enable support for the new language standard. The new C11 features are
|
||||
backwards-compatible and are available as an extension in all language
|

modes.</p>
|

|
||||
<p>All warning and language selection flags which previously accepted
|
||||
<code>c1x</code> have been updated to accept <code>c11</code>. The old
|
||||
<code>c1x</code> forms have been removed.</p>
|
||||
|
||||
<p>Clang 3.1 adds a family of <code>__c11_atomic</code> builtins corresponding
|
||||
directly to the <code>_explict</code> versions of the C11 atomic functions.
|
||||
This means that C11's <code><stdatomic.h></code> can be implemented in
|
||||
a small set of trivial macros. </p>
