[Bug other/92484] In tree build of ISL 0.22 fails: requires C++11
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92484 --- Comment #1 from Jonathan Wakely --- (In reply to Romain Geissler from comment #0) > Is there any official way to build gcc with another C++ standard by default > ? And is in-tree build of libs like gmp/mpfr/mpc/isl still supported or > officially declared deprecated and shall not be used anymore ? It's supported but the recommendation is to use the versions known to work. If ISL 0.22 doesn't work in-tree, don't use that version in-tree.

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=92484 --- Comment #2 from Romain Geissler --- Yes this is what I did, I reverted back to ISL 0.21 which for me has been working for the past months (don't know if it's a recommanded version though). Shall we keep this bug open to track the upcoming support of in-tree 0.22 or shall it be closed ?

Or simply _not_ force any -std=XYZ for compiling in-tree mpfr/mpc/isl/gmp. I think we don't use that for stage2+ either, maybe just for stage1 but there using it in GCC "owned" modules should be enough. So yes, keep the bug open.
