* utils/hbmk2/hbmk2.prg
+ Added support for envvar HB_VISUALC_VER_PRE80 to signal
older MSVC versions (just like in Harbour builds).
+ Synced mscvarm optimization switches.
The sync between hbmk2 and Harbour build switches is
now done. The only - intentional - difference is that
hbmk2 won't set any explicit C compiler warning level,
but this also can be implemented later with optional
switches.
! Fixed regression in win/icc linker name.
