Hi Stephan,
These warnings are being emitted by VC10 because std::streamsize is now unconditionally 64-bit, for large file support. (Inevitably, we missed one tiny thing in VC10 so large files aren't supported perfectly everywhere - but it's much better than VC9 and already fixed in VC11.)
Out of interest would you mind providing a reference to the "one tiny thing"? I rely quite heavily on huge file support and have so far got away with switching off _all_ my VC8/VC9 workarounds for VC10! Also, by any chance, has https://connect.microsoft.com/VisualStudio/feedback/details/677738/ifstream-... come your way yet? ;-) Many thanks, Gareth ************************************************************************ The information contained in this message or any of its attachments may be confidential and is intended for the exclusive use of the addressee(s).
