Alpha's <sys/poll.h> file was so far compatible with most of the other
archs (except SPARC). Since the introduction of POLLREMOVE it's
different. In Alpha:
#define POLLREMOVE (1 << 11)
+#define POLLRDHUP (1 << 12)
For the other archs:
#define POLLREMOVE 0x1000
+#define POLLRDHUP 0x2000
For Alpha the values should have been 1<<12 and 1<<13. Neither
POLLREMOVE nor POLLRDHUP have been in any glibc header. How widely are
they used elsewhere? Is it too late to change the Alpha definitions to
match the rest?
