Note that I don't add those options as default because
it still shows many false-positive (it seems not to consider
longjmp).
* vm_eval.c (stack_check): get rb_thread_t* as an argument
to avoid duplicate call of GET_THREAD().

it is in fast path.

* configure.in (__builtin_ctz): check.
* configure.in (__builtin_ctzll): check.
* internal.h (rb_popcount32): defined for ntz_int32.
it can use __builtin_popcount but this function is not used on
GCC environment because it uses __builtin_ctz.
When another function uses this, using __builtin_popcount
should be re-considered.
* internal.h (rb_popcount64): ditto.
* internal.h (ntz_int32): defined for ntz_intptr.
* internal.h (ntz_int64): defined for ntz_intptr.
* internal.h (ntz_intptr): defined as ntz for uintptr_t.

gap between GREEK CAPITAL RHO and SIGMA.

capitalize, and swapcase (with :lithuanian as a guard).
