- a reference to a still incomplete AquaA11FocusListener was used
- method declarations inside the class must omit the class name qualifier

The interesting discussion in http://gcc.gnu.org/ml/gcc/2012-03/threads.html#00455
pointed to the fnon-call-exception option to solve this problem. Thanks to Stephan
for starting this fruitful mailing list thread.

they are dirtied directly in the assembler code, so add them to the clobber list

destructing them via their baseclasses virtual destructor would be possible but
some aggressive compilers use their type knowledge to destruct them directly.
For such cases these destructors need to available as inlines or as visible symbols
which does not always seem to be the case for implicitly declared destructors.

also a minor cleanup of that code part

else clang/libc++ cannot decide between bool and a reference into a bit-vector specialization

also mark some related local functions as static

Work around libc++'s specialization for fill_n() not returning the matching OutputIterator.

The TR1 containers don't support dynamic hash functions provided in their constructor.
Having the hash functor as part the hash container's type is cleaner anyway.

the function call convention for IA32 apps on OSX documented at
http://developer.apple.com/library/mac/#documentation/DeveloperTools/Conceptual/LowLevelABI/130-IA-32_Function_Calling_Conventions/IA32.html
indicates that ECX is not preserved.
