* PR c++/54955 - Fail to parse alignas expr at the beginning of a declarationDodji Seketeli2012-10-314-5/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | In this PR, g++ embarrassingly fails to parse the simple alignas expression below: alignas(double) int f; even though the simple-declaration production in Clause 7 suggests otherwise.
