Description:
------------
The table:

static const php_hash_uint64 rc[R + 1] = {
...
    L64(0xbd5d10f4cb3e0567),
...

uses unsigned data of 64-bit size, but it isn't declared as such. When the high bit is set, as above, this causes warnings (or errors, if -Wall is present).


Reproduce code:
---------------
The fix is trivial.  In the sequence:

#elif SIZEOF_LONG_LONG == 8
#define L64(x) x##LL
typedef unsigned long long php_hash_uint64;

for example, in ext/hash/php_hash_types.h, the macro should be written as:

#define L64(x) x##ULL

instead.
