always use this startup. If you know that you can use HB_STATIC_STARTUP

This is only necessary when you want to create binary libs using
MSC in C++ mode (-TP switch) and later this binaries will be linked
by standard C linker with [x]Harbour programs. I strongly suggest
to for 3-rd party developers to use MSC in standard C mode to create
libraries which can be used with standard C compilers. This will
eliminate the problem and we will be able to set C++ initialization
as default for MSC in C++ mode. Druzus.
