------- Comment #4 from nathan at gcc dot gnu dot org 2007-10-14 16:26 ------- DR 325 describes the ambiguities in the standard. There are a number of possible solutions to accepting this syntax, with different implementation complexities, and it is not clear what the desired outcome is.
As there is a simple workaround -- adding parentheses -- which is unambiguously correct, I do not see a need to speculatively implement a language extension here. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33754
