@@ -336,6 +336,8 @@ On Visual C++ versions 6.5 and 7.0, `hash_value` isn't overloaded for built in
arrays. __boost_hash, __hash_combine and __hash_range all use a workaround to
support built in arrays so this shouldn't be a problem in most cases.
On Visual C++ versions 6.5 and 7.0, function pointers aren't currently supported.
`boost::hash_value(long double)` on GCC on Solaris appears to treat
`long double`s as doubles - so the hash function doesn't take into account the
full range of values.
