BorlandC++ fix

All BorlandC++ compilers versions higher than 5.2 think that structure
OPENFILENAMEW is longer than it must be. (file include/commdlg.h proves
this)
Because of this, for example, following:

perl -MTk -Mstrict -we "MainWindow->new->getOpenFile"

 will fail on WinNT-4.0 (with Tk error "CDERR_STRUCTSIZE") but will succeed
on Win2000

I currently can't see any benefits of such incompatibilities, most probably
this is another Borland's incompatibility bug.

That is why I want introduce "-D_WIN32_WINNT=0x0410" switch to suppress this
behaviour and not to go into Win2000 when unnecesarry.
