The ll width specifier isn't supported by all msvcrt version. Equivalent for target would be I64. Beginning with OS Vista (IIRC) the msvcrt printf/scanf faimily routines are supporting ll, too. But to avoid breakage with older msvcrt, gcc has to warn about it. >> How can we track >> down why it works for him, but not for me? > > First step would be making _sure_ that he isn't accidentally > using the __mingw_* variant by looking at the preprocessed source > (the -E switch of gcc). If he really isn't, then I don't know: Kai? See msvcrt.dll's version. It is related to it.
