Dear Andrew,
Yes, it is a potential issue.

Subject: [naviserver-devel] warning, shift count undefined behavior
Hm, this warning sounds kind of scary:
sockfile.c(351) : warning C4293: '>>' : shift count negative or too big,
undefined behavior
That's in the Windows-only implementation of pread(), in nsd/sockfile.c:
overlapped.Offset = (DWORD)offset;
overlapped.OffsetHigh = ((DWORD)offset >> 32);
I don't know if it's a real problem or how to fix it.
