The whole repo can now be built with iso C standard (c89, c99 and c11) Signed-off-by: Simon Zeni <simon@xxxxxxxxxxxx> --- References to the compiler extension `typeof` have been changed to `__typeof__` for portability. See [GCC's documentation][1] about `typeof`. I've added the definition `_POSIX_C_SOURCE` in the source files that are using functions not defined in by the POSIX standard, fixing a few occurences of `sigset_t` not being defined. I've also added the definition `_BSD_SOURCE` in `setup.c` and `syscall.c` for respectively the `madvise` function (I know that `posix_madvise` exists, but there is not equivalent for `MADV_DONTFORK`), and `syscall`.
