Hi, I've been trying to read up on the ABI compatibility between C++11 and C++03/98, and one of the pages that I've read is http://gcc.gnu.org/wiki/Cxx11AbiCompatibility This wiki page addresses GCC 4.7. I've read a comment on stackoverflow (http://stackoverflow.com/questions/13383124/g-std-c0x-and-compatibility) by Jonathan Wakely that some of these issues would change or be resolved in 4.8. Elsewhere I've read that 4.8 would introduce more breakages compared to 4.7. What is the status of these issues in 4.8 and 4.9? Is there any chance of someone in the know updating the wiki? Cheers Lars
