To answer a few more questions:

1. All future Linux ports are required to use the new generic ABI definitions
   (defined in include/uapi/asm-generic).  This is intended to permanently
   address the issue of platform-specific ABIs (which was an artifact of
   the misguided idea of providing binary compatibility with legacy Unices
   on some platforms.)

   So all future platforms will support termios2.

2. After doing some digging, it seems like the only platform that doesn't
   support termios2 is Alpha... ironically because it had c_ispeed and
   c_ospeed in its termios structure already.  However, at least somewhere
   along the line, the kernel infrastructure for supporting this as a one-
   off without BOTHER seems to have broken.  I have contacted the serial
   and Alpha maintainers and proposed a very simple solution, but it would of
   course only work on new enough kernels.



Final question:

What platforms and Linux kernel versions does glibc support these days?
