    Well, I only use double and int though, but I suppose it means the double. Is the actual number too long for double (don't remember ranges)?

    It is with 32-bit longs, as in 32-bit systems. According to the rules of the standard, the compiler has to see if it fits into a int, and if not, try a long. If that also doesn't fit, the behaviour is, I believe, undefined. Or perhaps implementation-defined. The point is, since some platforms GCC compiles for have larger longs than ints, it really tries them in order - and when it fails, it reports that the literal won't fit into a long, since that's the last thing it tried.

    I'm still confused as to why your GCC doesn't give any warnings.
    All the buzzt!
