For me, it's ok; but I thought it were there for purpose.  Maybe POSIX
doesn't define that speed_t can only contain Bxxxx constants, or some
(maybe non-POSIX) systems are broken in this aspect, or maybe some can
get away with B9600=9600 and so they don't really need constants...

This way, we hopefully won't break on anyone's system...  Or, that's what
beta-testing is for? :)
