d6a5c9c435 New attempt at fixing the function pointer hash on the Sun compilers.
I think I was barking up the wrong tree - it could be that when calling
hash_value with a function pointer the compiler was choosing the
hash_value(bool) overload over the hash_value(T*) overload, so instead I'm
trying to call the correct one by giving it a template parameter. Another
alternative would be to calculate the hash function inside boost::hash.

Unfortunately, if I'm right, this means that other calls to hash_value will go
wrong for function pointers.

cd2d453735 Fix my botched attempt at supporting function pointers on Sun's compilers.
Also, now only applies the workaround to function pointers, non-function
pointers are treated as before. I might need to apply the special case to
member function pointers as well.

8ff9a154ad 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.

7d6f6fe0b4 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.

1. hash_float is no longer dependent on the main hash header.

it isn't part of the documented interface.
