--- Comment #23 from Jonathan Wakely <redi at gcc dot gnu.org> --- That would be an ABI change for C++ functions like: void func(int8_t); Such functions would get a different mangled name after the fix, so would no longer link to code compiled before the fix. They would also be incompatible with code compiled by Solaris compilers that use the un-fixincluded system headers (I'm not sure if that matters though, is there binary compatibility between G++ and Solaris CC?) As the target maintainer it's your call whether that's acceptable, I'm just pointing it out.
