Warnings when compiling the Hurd

[Thomas Schwinge]

Hello!

| <youpi> btw, I've realized they is a bunch of warnings while compiling
|         the Hurd, these should probably deserve killed
| <azeem> somebody should try with gcc-4.2/gcc-4.3 :)

Here is the list when compiling with GCC 4.1.  So far, I didn't try with
4.2 or 4.3.

This was with plain Hurd cvs HEAD, plus my ``struct stat'' patch, to make
it build at all.

It may be that some warnings are missing from this list, as I started
working on eliminating them on some afternoon a week ago or so, but I
don't remember if I assembled this following list before or after having
started eliminating them.  I guess I should simply install the few fixes
I did so far or post them here for your perusal.

I'll also go about updating the ``struct stat'' patch, according to
Samuel's and Roland's suggestions, thanks!


Such an analysis should also be done for (the Hurd and Mach parts of)
glibc!


I stripped the `pfinet' warnings (mainly from the imported Linux 2.2.x
code -- we should perhaps be compiling this with fewer optimizations
(`-fno-strict-aliasing' comes to mind) and with fewer compiler warnings
enabled?) and `ufs' warnings (I don't know if anybody is using this code
anymore?).
