Nice :-)

It would be best if you could split it up into a series of patches, each
for one type of warning, along with an explanation... This would make
reviewing much easier. (For me at least.)

As these are only warning fixes, I guess it's not crucial though...

Using -std=c99 and -pedantic is not desirable: it will forbid GNU
extensions (such as nested functions) -- but the Hurd code is not meant
to be compiled with anything but GCC, so we don't care about portability
at all! :-)

Not really related to your patch -- but I wonder, did they really assign
copyright to HurdFR? I kinda doubt that...

As for the rest, Thomas analysed it in much more detail than I had the
patience for :-)
