C11 and <stdatomic.h>

[Sebastian Huber]

Hello,

what is the status of the <stdatomic.h> feature of the C11 standard in GCC?  On 
the wiki page http://gcc.gnu.org/wiki/C11Status GCC 4.7 is listed as the first 
supported version.  In case I build for example an ARM EABI cross compiler I 
get no <stdatomic.h> header file.  Should the C library provide it?  For 
example FreeBSD uses

http://svnweb.freebsd.org/base/head/include/stdatomic.h?view=markup&pathrev=234958

I am a bit confused since the wiki page doesn't mention that the <stdatomic.h> 
is also a library issue e.g. as for "Macros for Complex values".
