Are other people building GCC seeing these messages during the build: cc1plus: warning: -Wabi won't warn about anything [-Wabi] cc1plus: note: -Wabi warns about differences from the most up-to-date ABI, which is also used by default cc1plus: note: use e.g. -Wabi=11 to warn about changes from GCC 7
It doesn't seem to be causing any problems in the build (even bootstrap) but I am wondering why it is there. It seems to be happening when using the latest (just built) g++ to build libstdc++ so it shouldn't be related to the system GCC that I am using to build with. I didn't find any mention of it in the gcc or libstdc++ mailing lists when I looked or find any bugzilla report. Steve Ellcey
