This is tempting. Bison being a maintainer tool, I guess its audience has typically better compilers than on average. So I expect it would not be a problem to have the same requirements. I also see that there are also some uses of a declaration in the for-loops, but surprisingly few: akim@erebus ~/src/gnu/coreutils $ git grep -P 'for \(\w+ \w+' ChangeLog-2005: (parse_options): Give a diagnostic for (but still accept) the gl/lib/rand-isaac.c: for (int i = 0; i < 4; i++) /* scramble it */ gl/lib/rand-isaac.c: for (int i = 0; i < 4; i++) /* scramble it */ src/csplit.c: for (size_t count = 0; ; count++) src/ls.c: for (int i = 0; i < 12; i++) src/stat.c: for (char const *src = dst; src < p; src++) src/stat.c: for (int i = precision; i < 9; i++) (And the first two seem to be #if 0'd). Is it considered ok too?
