    Some warnings I don't understand...

    I have some code which compiles fine on my computer with out any warnings, but on a friend of mines it compiles but I get a lot of warnings, how ever it still works as it should, the warnings I get are :
    Code:
    /usr/include/ppc/ansi.h:2:3: warning: style of line directive is a GCC extension
    In file included from /usr/include/machine/ansi.h:33,
     from /usr/include/sys/types.h:74,
      from /usr/include/stdio.h:64,
       from Talking.c:2:
    and
    Code:
    Talking.c:4:3: warning: style of line directive is a GCC extension
    and
    /usr/include/ppc/types.h:76: warning: ISO C89 does not support `long long'
    I compile this with gcc on both comps with -ansi -pedantic -Wall

    They say that if you play a Windows Install CD backwords, you hear satanic messages. That's nothing; play it forward and it installs Windows.

    i dont' know about the style of line thing. I think I got it once but I don't remember what it was. I don know that ISOC89 does not support long long. That is a compiler extension.

    I read this and I don't quite get how to make the warning go away, since I haven't used any lon g longs...

    The problem is that it's #including the long long definition from a header file and it's being compiled along with your program. To get rid of the warning don't compile with -ansi or -pedantic. There might possible be a newer version of glibc out there that doesn't cause the warnings.
