Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |NEW Last reconfirmed| |2016-02-11 Ever confirmed|0 |1 --- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> --- Glibc includes sys/sysmacros.h conditionally based on: #ifdef __USE_MISC which is unfortunately always true for C++, because we define _GNU_SOURCE unconditionally (so this is a variation on PR 11196). I want to be able to stop defining that, probably for gcc7, but it's a big job.
