ffi-libc 0.1.1 has been released. This release fixes a major bug, where ffi-libc was still binding the libc global variables sys_errlist and sys_nerr, which glibc had deprecated and then removed, causing ffi-libc to not load. These variables are still available on BSD libc implementations. If the variables are not available, ffi-libc will ignore the FFI error and continue loading the rest of ffi-libc.

ffi-libc are FFI bindings to the libc library and allows accessing certain low-level C functions that Ruby does not (ex: alarm(2) and getifaddrs(3)).
