The goal for gnulib is not necessarily strict C89 compliance, but rather using C89 plus any extensions available that make life easier. In this case, the compiler supports 'long long' as an extension, or we would not have defined HAVE_LONG_LONG_INT. Are you sure your addition of -ansi -pedantic is happening before the autocong probe prior to HAVE_LONG_LONG_INT? But it _does_ seem reasonable that we should mark up our headers with __extension__ to make gcc shut up about places where we knowingly use non-C89 constructs. So feel free to continue to report these issues, and/or patches. -- Eric Blake
