* bin/hbmk.bat
+ Added automatic architecture detection on Windows NT and above.
+ Added automatic compiler detection on Windows NT and above.
(mingw, msvc, bcc32 and owatcom are detected - in that order)
The given compiler should be properly setup, with compiler
executable in PATH or current dir.
; NOTE: This makes it possible to get rid of all hbmk_b32.bat and
hbmk_vc.bat files and at the same time automatically
add support for OpenWatcom and MinGW for all our tests,
examples, etc. I'll replace all special hbmk_b32.bat
and hbmk_vc.bat files with generic local hbmk.bat files,
which can be used with any supported compilers.
