Thread: Some Error messages 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

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...
