Well as discussed already, our stat() emulation on Windows does
multiple syscalls, so it's a slight improvement. However, it looks
like we might be missing a further opportunity here... Doesn't
Windows already give us the flags we need in the dwFileAttributes
member of the WIN32_FIND_DATA object that the Find{First,Next}File()
functions populate?
