make FILE a complete type for pre-C11 standard profiles
C11 removed the requirement that FILE be a complete type, which was deemed erroneous, as part of the changes introduced by N1439 regarding completeness of types (see footnote 6 for specific mention of FILE). however the current version of POSIX is still based on C99 and incorporates the old requirement that FILE be a complete type. expose an arbitrary, useless complete type definition because the actual object used to represent FILE streams cannot be public/ABI. thanks to commit 13d1afa46f8098df290008c681816c9eb89ffbdb, we now have a framework for suppressing the public complete-type definition of FILE when stdio.h is included internally, so that a different internal definition can be provided. this is perfectly well-defined, since the same struct tag can refer to different types in different translation units. it would be a problem if the implementation were accessing the application's FILE objects or vice versa, but either would be undefined behavior.
