ROOT MSVC debug builds (and version of MSVC) are now compiled with -MDd,
not -MD. This means debug builds will link against the debug versions of
the runtime libraries. This change has to be propagated to all object
files - any debug build of root (no matter what version of MSVC) has to
be completely re-built!

This and MSVC8 incompatible flags had to be changed for sub-modules'
Makefiles, too.
