Thanks for the report, but this is surprising.  Doesn't Alpha GNU/Linux
define TIOCGWINSZ in /usr/include/asm-generic/ioctls.h?  And isn't that
file #include'd, indirectly, by <sys/ioctl.h>?

If not, does Alpha GNU/Linux define TIOCGWINSZ at all, and how does it
define it?  I thought TIOCGWINSZ was common, and I'm particularly
surprised to not find it on a GNU/Linux system.
