What did you do?

run vgo env CC

What did you expect to see?

gcc

What did you see instead?

clang

This also caused a compile error if you build a simple program like:

package main 

import "net/http"

func main() {
	http.ListenAndServe(":8080", nil)
}
vgo build -v .

@lgarithm have you tried go1.11beta2? vgo is now deprecated, since it was only the prototype tool that is now part of Go itself.

@mvdan I tried https://dl.google.com/go/go1.11beta2.linux-amd64.tar.gz, it works.
Thanks!
