I did it in that order because I wanted to test the error condition
on the FILE before actually checking errno. The C99 draft that I have
does not say anything about errno, but the man page on my GNU/Linux
machine does say explicitly that errno doesn't get set during
a call to ferror.

I can try reversing them, though... Let me know if you think I should.
