1) if you don't change the type of type to be int, it will give you bogus
errors, but
the real problem is that some of the files do not compile.

2) opnames.h is autogenerated by dist. IIRC there is no problem with it
(see 1).

3) I have GOEXPERIM set to ''. You need to set a ton of variables, out of
the top of my head,
assuming you are not cross-compiling:


GOROOT=/sys/src/golang #where the go repository resides
GOOS=plan9
GOARCH=$objtype
GOHOSTARCH=$cputype
GOBIN=/$objtype/bin
GOPATH=/sys/src/go #wher your go stuff resides
GOARM=5 #or 6 or 7, depending on your machine's support of floating point.
GOEXPERIM=''
