// attached to a section definition symbol. The PE format defines a
// number of different aux symbol formats: format 1 for function
// definitions, format 2 for .be and .ef symbols, and so on. Format 5
// holds extra info associated with a section definition, including
// number of relocations + line numbers, as well as COMDAT info. See
// https://docs.microsoft.com/en-us/windows/win32/debug/pe-format#auxiliary-format-5-section-definitions
