fbe0c3eeca Add overloads of hash_value for more built in types. They're not strictly 
needed and aren't in the original specifiction but they avoid a warning. See
ticket #1095 for details.

d25ca5a376 Put the borland workarounds back - it still seems to need them. Will probably 
have to do something else on top of this for any problems this causes.

for integers in the tests.

9430503530 Move the hash extensions into their own header, which hopefully makes the 
extension implementation a little clearer. It also fixes a problem where the
visual C++ include once pragma was preventing the extensions from being loaded
on the second include.

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.

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.

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.

15d97d95e7 Implement hash functions for built-in arrays. Uses partial specialization
