[PATCH] gccgo patch 6-8 (last) (9)

[Svante Signell]

Hi,

Attached are patches to enable gccgo to build properly on Debian
GNU/Hurd on gcc-4.7 (4.7.3-4).

patch6.diff: src/libgo/go/syscall/exec_gnu.go: New file, copied from
exec_bsd.go, with function raw_ptrace returning ENOSYS.

patch7.diff: src/libgo/go/syscall/wait.c: Define WCONTINUED empty as a
workaround for now.

patch8.diff: src/libgo/mksysinfo.sh: Fix problems for gcc -fdump-go-spec
not catching #define EWOULDBLOCK EAGAIN. For #define st_dev st_fsid
likewise.

Some build instructions, notes and test programs will be sent in a
separate mail. gccgo has been test built sucessfully :) Binaries (.deb)
are available on request.

HTH,
Svante
