Change Log

Use declarations for standard classes, so that the library doesn't need to include all of their headers
Deprecated the <boost/functional/hash/*.hpp> headers. Now a single header, <boost/functional/hash.hpp> is used.
Add support for the BOOST_HASH_NO_EXTENSIONS macro, which disables the extensions to TR1.
Minor improvements to the hash functions for floating point numbers.
Update the portable example to hopefully be more generally portable.

Support for long long, std::complex.
Improved algorithm for hashing floating point numbers:
- Improved portablity, as described by Daniel Krügler in a post to the boost users list.
- Fits more information into each combine loop, which can reduce the the number of times combine is called and hopefully give a better quality hash function.
- Improved the algorithm for hashing floating point numbers.
- On Cygwin use a binary hash function for floating point numbers, as Cygwin doesn't have decent floating point functions for long double.
- Never uses fpclass which doesn't support long double.
- Ticket 1064: Removed unnecessary use of errno.
Explicitly overload for more built in types.
Minor improvements to the documentation.
A few bug and warning fixes:
- Ticket 1509: Suppress another Visual C++ warning.
- Some workarounds for the Sun compilers.
