[Boost-build] Patch to allow bjam bootstrap on WIN64

Hey guys,
I was toying around with bjam from CVS today and I noticed that
jam0.exe would crash when built for x64.

It seems the bug is that ShortPathToLongPath function uses DWORDs for
indexes while at the same time relying on them wrapping around; this
doesn't work well when indices are 64-bit (DWORD is still a 32-bit
datatype).

This patch make the bootstrap succeed with a x64 cl, but I'm not
entirely sure it's correct for 32-bit compilation.

Best regards,
Andreas
