aken: clean up debug strings mahaf: use checked/free version of aken depending on config. refactor to eliminate goto. hpet: avoid undefined unmap if HPET not found whrt/*: make sure all counter class data is initialized whrt: prefer QPC over PMT (it's much faster?!) winit: add some instrumentation wutil: win_exe_dir and win_sys_dir shouldn't end in slash. fixed. This was SVN commit r5116.
