! Fixed potential GPF in executable type detection.
Fixes GCC 4.3.1 warnings in openSUSE 11.

* Harbour level HB_DBG_*() functions renamed to __DBG*() to
reflect their internal nature.
- Removed old __VM*() synonyms to Harbour level __DBG*() functions.
INCOMPATIBLE.
! Fixed a few minor doc bugs along the way.
