* shlib-versions: Match alpha*.

Browse Source 
* sysdeps/unix/sysv/linux/alpha/syscalls.list: Add adjtimex.
        * sysdeps/unix/sysv/linux/alpha/adjtimex.S: Remove.
        * sysdeps/alpha/fpu/bits/mathinline.h (isunordered et al): New.
        Implement copysign* with and without __ prefix.
        Likewise for fabs; use builtin for gcc 2.8.
        (floor*): New.
        (fdim*): New.
        * elf/elf.h (EF_SPARC*, EF_ALPHA*, SHT_ALPHA*, SHF_ALPHA*): New.
        (R_SPARC*): Match current v9 ABI.
        * sysdeps/wordsize-64/stdint.h (intptr_t): Is a long.
        * sunrpc/clnt_udp.c (clntudp_call): Use socklen_t.
        * sunrpc/pmap_rmt.c (clnt_broadcast): Likewise.
        * sunrpc/svc_tcp.c (svctcp_create, rendezvous_request): Likewise.
        * sysdeps/generic/getresgid.c: Use prototype form because of warning.
        * sysdeps/unix/sysv/linux/getdents.c: Likewise.
        * sysdeps/unix/sysv/linux/alpha/adjtime.c: Likewise.
        * sysdeps/unix/grantpt.c (argv): Fix consts.
        * sysdeps/unix/sysv/linux/getpt.c: Include <string.h>
        * sysdeps/unix/sysv/linux/sigaction.c: Likewise.
