There's no copyright header on this file.

A few others a missing copyright headers too, but they're all simple
.h files, so not critical. This, though, is a major .c file so I think
it really should have a copyright header present. IIUC, this is not
your code, but rather copied from the google repo, so ought to get the
original author to update this.

There's loads of fprintfs() throughout this file - it really needs to
be fixed to use error_report()
