Workaround for gcc 4.2.x.

g++ 4.2 (and possibly earlier) apparently call a copy
constructor when passing a temporary to a function
that takes a const reference. Added code to allow
copy-constructing the AI*Access classes for this
compiler.

g++-4.2.x also bails out when it encounters files that
do not end on a newline. So, also added those where
they were missing.
