It appears that autoconf only believes a type is real if you can typedef it to

breaks down for scripts that want to make sure FILE is a real type.
Oh c'mon! we're going to revert this needed fix just because of
autoconf?
By the time 8.0 rolls around, autoconf will be fixed and there
will be some standard patch/workaround for old autoconf.
Let's just roll forward with this. We've needed it for years.
Can you please explain the "needed" part? What are gains apart from pure
aesthetics and removing some type dependency from libc that otherwise
needs to know actual storage type of pthread_t&Co? Neither is worth
breaking zillion autoconf scripts out there IMHO (not everybody uses up
to date ports and ports in general!).
