// There's actually 3 places these checks all come into play:
// 1. When the generated source is compile into .o files, the header check
// happens. This is checking the protoc used matches the library being used
// when making the .o.
// 2. Every place a generated proto header is included in a developer's code,
// the header check comes into play again. But this time it is checking that
// the current library headers being used still support/match the ones for
// the generated code.
// 3. At runtime the final check here (GPBCheckRuntimeVersionsInternal), is
// called from the generated code passing in values captured when the
// generated code's .o was made. This checks that at runtime the generated
// code and runtime library match.
