Hello! Attached ports go to ALPHA architecture. There are however several problems with the build: a) Bootstrap compare failure in the gcc/go directory due to binutils bug [1], fixed in latest binutils SVN, use --disable-bootstrap b) alpha doesn't define "struct user_regs_struct" from which "type PtraceRegs" is derived. I have manually created PtraceRegs from pt_regs structure and patched generated libgo/sysinfo.go in build directory after the build broke. However - the comment from sys/user.h says that this file is for GDB and GDB only... c) some weird issue with double definition of "const _SOCK_NONBLOCK" in gen-sysinfo.go and consequently sysinfo.go.
