46654045d7 Comment out an assert which is giving bogus failures. On platforms where it isn't possible to detect NaN or infinity the full hash computation is performed on them. For NaN the result doesn't matter (since NaN != NaN), for infinity it should always give the same result), so the calculation works but unfortuanately, I don't know how to correctly check that v is what I expect in the assertion. 
I could use a different hash function when I don't have fpclassify/fpclass but that shouldn't be necessary.

d8c636ef9f Tweak the float hashing algorithm to perform fewer calls to ldexp for some 
types and possibly generate a better hash value.

version of boost::hash_value<complex> in it. So fix that.

3ce1a740b7 Don't forward declare STL containers when using STLport - this is slightly over the top as the forward declarations seem to work on mingw-3_4_4-stlport-5_0, so maybe it's just a Visual C++ problem, but at this stage I'd rather keep things simple.

17d5f71c35 Remove TODO note to self. 
For the record: I removed the overload because it was causing an ambiguity that I was too lazy to work out at the time. It turned out this was because wchar_t was defined as unsigned short - using BOOST_NO_INTRINSIC_WCHAR_T was the right way to deal with this so the overload no longer needs to be disabled.

514757c312 Hold your nose, it's a Visual C++ 6.5 workaround. For some reason it requires 
boost::hash to define operator() taking const and non-const arguments.

1d5bfbcc9c Since all the hash functions are now declared in a single header, there's no 
need for the call_hash hack on compliant compilers. So only use it on
compilers where it's needed.

5a5bbbf403 Make hash_float.hpp use its own combine function. This serves two purposes: 
1. hash_float is no longer dependent on the main hash header.
2. hash_float(0) == 0 which makes it easier to implement hash<complex>(),
although this might lead to users assuming that it can be expected even though
it isn't part of the documented interface.

dbed5ebafa Use non-const references on Visual C++ 6.5 to work around a bug with array references.

15d97d95e7 Implement hash functions for built-in arrays. Uses partial specialization 
instead of function overloading - which disobeys the specification of
the extension (hash_combine is defined in terms of hash_value, but hash_value
doesn't deal with every case now).
