--- Comment #18 from Jonathan Wakely <redi at gcc dot gnu.org> 2012-01-11 16:50:09 UTC --- Regarding the remaining failures, it appears to be a front-end issue. Fixing it in the library could be done with an autoconf macro to detect that the testcase in comment 13 works. If that macro isn't defined, use the init function instead of the init macro. I'm not sure if/when I'll be able to work on that.
