// Define a minimal subset of the definitions needed to build a loadable fake
// GSSAPI library. The bindings follow RFC 2744. The code follows the RFC
// faithfully with the possible exception of `const` qualifiers for some
// function arguments.
//
// Note that //net/http/http_auth_gssapi_posix* functions depend on the gssapi.h
// as found on the host platform. For test purposes file does not depend on the
// system gssapi.h in order to reduce sensitivity to the host environment.
//
// These declarations follow RFC 2744 Appendix A with the exception of using
// C++isms in some places.
