There are a few reasons for the current mess, and yes it should be cleaned
up but going to POSIX termios exclusively isn't the correct solutions
because, not all machines support POSIX termios, you are implementing the
POSIX interface (isatty()) and need to do it in a similar way to the
system implementation of the same.
Anyway, acording to the beta 3 source, TCGETA is only used if sunos4 is
defined, and termio.h is only included if sunos4 is defined or TIOCGETA
is not defined and that is to get the TIOCGETA define.
