--- Comment #6 from Manuel López-Ibáñez <manu at gcc dot gnu.org> 2013-01-10 13:54:22 UTC --- Perhaps you could add an entry to the FAQ: http://gcc.gnu.org/wiki/FAQ so when people google for the error, they understand what the problem is. The FAQ should also mention this bug. Because it is possible that this issue won't be fixed in the next few years.
