 See the thread "[http://lists.gnu.org/archive/html/chicken-hackers/2007-
 10/msg00017.html file-size not reporting correct size on big files]" on
 chicken-hackers.

 The problem is that chicken uses {{{unsigned-int}}} as the type of
 {{{stat}}} structure members (and probably in other places, too!), which
 causes problems on 32-bit architectures.  The {{{stat.st_size}}} is of
 type {{{off_t}}}, which ''can'' be 64-bit on some systems, if compiled the
 right way.  When using an {{{unsigned-int}}}, huge file sizes (bigger than
 1Gb) overflow/get truncated.  Simply using an int64 is not the solution
 either, as you don't know what size {{{off_t}}} is actually.  If it ''is''
 32-bits you would be getting file sizes that are corrupted even more.
