In the context of mentioning the -std=gnu89/-std=c89 workarounds this tries to say that when you use -fpermissive you can get the same behavior when you rely on -std=c99 (for example for C99 inline semantics) or later (GCCs default is -std=gnu17). But I agree singling out C99 inline semantics is confusing (C99 is the next standard after C89). Note all the warnings that turned into errors are for features of C89 (or legacy C) that were removed from C99. Richard. > > -- > -- regards > -- > -- Matthias Urlichs >
