--- Comment #8 from Frank Heckenbach <f.heckenb...@fh-soft.de> --- (In reply to Marek Polacek from comment #4) > Also note that GCC 14 warned about this: > > $ xg++-14 -c 120917.C -fconcepts-ts > cc1plus: note: ‘-fconcepts-ts’ is deprecated and will be removed in GCC 15; > please convert your code to C++20 concepts I may warn if you use "-fconcepts-ts", but my point is that I never used it in the first place. Also, GCC 14 would be much too late, since it was introduced (without a warning) it GCC 12 or earlier.
