appropriate sign-extension is performed on machines with

sizeof(long) > 4.
|

|

* sysdeps/unix/sysv/linux/alpha/sysdep.h: Rename __NR_get?id

EWOULDBLOCK -> EAGAIN mapping was unnecessary since

EWOULDBLOCK==EAGAIN under DEC Unix and Linux/Alpha).
|

|

* sysdeps/alpha/divrem.h: Use retaddr instead of ra as the return

address register in the .frame directive.
