Re: undefined behaviour findings in bitset

Hi Akim,

In the first patch:
> +          for (bitset_windex windex = bitno / BITSET_WORD_BITS;
> +               (windex - woffset) < EBITSET_ELT_WORDS; windex++)

This is C99 syntax. If you don't add 'c99' as a dependency of your
module, the module will not compile with GCC versions < 5.1.0 with
their default settings.
