Hi I plan to build (and use) GCC 15 right after relesase. Building GCC takes several hours on my computer, so I would prefer to get it right at the first try. Does building the std module require any configure option? I tried `import std;` on compiler exporer and doesn't seem to be available there. I also looked at https://gcc.gnu.org/gcc-15/changes.html Perhaps should i compile it myself before use so that it is available in gcm.cache? If thats the cas, where is std.cc going to be installed? Thanks so much
