Changed locally to: libstdc++: Include range_access.h from <optional> and <stacktrace>
This implements resolutions for LWG4131 and LWG3625 (also part of 4.8. section of the P3016R6). As for any other issues LWG issue changes are applied as DR for the oldest applicable standards: * <optional> (LWG4131): C++26, since optional range support * <stacktrace> (LWG3625): C++23, since introduction On Fri, May 15, 2026 at 7:05 PM Tomasz Kaminski <[email protected]> wrote: > > > On Fri, May 15, 2026 at 6:55 PM Jonathan Wakely <[email protected]> > wrote: > >> Oh, the subject line says "and <valarray>" but that isn't covered by the >> patch. >> > Thanks; I will fix that.
