Changes between Initial Version and Version 1 of Ticket #60638, comment 5

initial	v1
1	1	{{{thread_local}}} always implies {{{std=c++11}}} or greater. <https://en.cppreference.com/w/cpp/keyword/thread_local>
2	2
3		I had a conversation with Marcus about whether setting {{{compiler.thread_local_storage yes}}} should imply at least {{{~~std=c++~~11}}} and that was felt to be completely unacceptable and it should always be separately specified, so therefore you have to specify both.

5	5	don't forget that many build systems will test for certain standards and use them if available. Just because the build line indicated {{{-std=gnu++14}}} on this particular system, it does not necessarily mean that the software actually requires that. Just that it used that during this build. Not a big deal -- it will probably just mean that ports that might have built with an older compiler will be forced to build with a newer one, but I know you don't like that.
