* pack.c (htov16): converts endian using swap16. htov32(), hton16,
hton32 as well. [ruby-talk:85377] * pack.c (swap16): swap 2 bytes no matter how big short is on the platform. swap32() is also prepared. * numeric.c (rb_num2int): returns long to preserve information. rb_fix2int(), rb_num2uint(), rb_fix2uint() as well. [ruby-talk:85377] * numeric.c (rb_num2uint): should not check for value range if the source value is negative. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@5075 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
