Hi Jorg,
Great work! I'll put in these changes into the repository, just I need you to
fill out the mini-COO (certificate of origin) below. The description would be,
I guess, "patches to compile BCP under VC++.NET" or something similar.
BTW, could you try whether one could include <ctime> instead of <time.h>?
After all, ctime is the correct C++ header, but I know that it doesn't work on
some systems.
Thanks,
--Laci
