Hi,

A similar patch aimed for powerpc (commit ab10727) had the following
definitions:

#define TCGETA    0x40147417
#define TCSETA    0x80147418
#define TCSETAW 0x80147419
#define TCSETAF  0x8014741c

On Alpha, if I do something like printf("TCGETA = 0x%08x\n", TCGETA);
I get TCGETA = 0x40127417, but on an intel/x64 I get 0x5405.
Is this something we need to consider here?

Regards

Magnus
