behavior has changed based on a non-default value
for that setting.
For example, when `GODEBUG=http2client=0` is set,
`/godebug/non-default-behavior/http2client:events`
counts the number of HTTP transports that the program
has configured without HTTP/2 support.

## Default GODEBUG Values {#default}

When a GODEBUG setting is not listed in the environment variable,
its value is derived from three sources:

	// doesn't have any ANSI escape sequences in it. (TERM=dumb is
	// insufficient; if the user specifies CGO_CFLAGS=-fdiagnostics-color,
	// GCC will ignore TERM, and GCC can also be configured at compile-time
	// to ignore TERM.)
	stderr := p.gccErrors(b.Bytes(), "-fdiagnostics-color=never")
	if strings.Contains(stderr, "unrecognized command line option") {
