... until GLib is ported to platform-of-the-week (Hurd? Plan 9? Windows 8?)
which has interesting fields that weren't in the traditional "struct stat";
at which point it either becomes non-comprehensive on the new platforms
(missing information that the new platform provides), or variable-size
(#ifdefs), or an ABI break on existing platforms (GLib 4). Comprehensive,
same layout on all platforms, fixed layout over time: pick any two.
GFileInfo is opaque/extensible/indeterminate-size precisely so that the fact
that its layout changes over time is not an ABI break.
