hurd_ihash

[Bas Wijnen]

Hi,

I was just looking at all the warnings which were produced by the code. 
 Most of them are not a problem at all ("unused variable" followed by 
"FIXME: do something with this", for example).  There are some 
"assignment makes integer from pointer without a cast" warnings from 
using atomic_compare_and_exchange_val_acq on pointers, which I guess is 
no problem either (although getting rid of the warning would be nice).
Also, a macro (MORECORE) in malloc.c:3337 (in various directories) gives 
a "statement has no effect"-warning.  This is also probably ok, but it 
would be nice if the warning could be removed.

One thing does seem like a (small) problem, though: in 
libpthread/sysdeps/hurd/pt-setspecific.c:33 and 38, functions named 
ihash_* are called.  They give "implicit declaration"-warnings.  Since 
<hurd/ihash.h> is included, I looked there.  There are hurd_ihash_* 
functions defined there, but just using those gives "too few arguments" 
errors.  I didn't look further into it, as I think someone who knows the 
code probably knows what's happening without even looking at it, so I 
would be wasting my time.  It seems like a bug to me, is it?

Thanks,
Bas
