             Bug #: 54955
           Summary: alignas example in gcc 4.8 changes.html won't compile
    Classification: Unclassified
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
        AssignedTo: unassigned@gcc.gnu.org
        ReportedBy: mib.bugzilla@gmail.com


gcc 4.8 changes.html file gives this example:
alignas(double) int i;

But the snapshot from Oct 14 2012 gives this message:
g++ -c -std=c++11 alignas.cpp
alignas.cpp:1:1: error: expected unqualified-id before 'alignas'
 alignas(double) int f;
 ^

If alignas is moved to the end of the declaration it compiles okay:
int f alignas(double);

doc error?

Could you also confirm whether c++11 keyword alignas is the same as c1x
_Alignas?

Thanks and regards
