I hijack this thread for some build test I did on the gcc-go branch as
of r166968 for x86_64-unknown-freebsd8.1 with:
../gcc/configure --with-gmp=/gcc/destdir/ --prefix=/gcc/destdir/
--enable-languages=c,c++,go
libgo fails to build with the following:
gmake[3]: Entering directory `/gcc/gcc-obj/x86_64-unknown-freebsd8.1/libgo'
gmake[4]: Entering directory `/gcc/gcc-obj/x86_64-unknown-freebsd8.1/libgo'

gmake: *** [all] Error 2
Adding "set -x" to the script gives a bit more details:
+ grep '^const PTRACE_EVENT_FORK' tmp-sysinfo.go
+ echo 'const PTRACE_EVENT_FORK = 1'
+ grep '^const PTRACE_EVENT_VFORK' tmp-sysinfo.go

This match:
# The registers returned by PTRACE_GETREGS. This is probably
# GNU/Linux specific.
regs=`grep '^type _user_regs_struct struct' gen-sysinfo.go`
if test "$regs" != ""; then
regs=`echo $regs | sed -e 's/type _user_regs_struct struct //'`
regs=`echo $regs | sed -e
's/\([^a-zA-Z0-9_]*\)\([a-zA-Z0-9_]\)\([a-zA-Z0-9_]*
[^;]*;\)/\1\U\2\E\3/g'`
echo "type PtraceRegs struct $regs" >> ${OUT}
fi
There also seem to be some trouble with the generation of
"./x86_64-unknown-freebsd8.1/libgo/sysinfo.go" as if I just comment
the lines above, the build dies with:

I'll continue to dig.
