cutealien 30b78dab9b Merging r6274 through r6281 from branch releases/1.8 to trunk.
- Updates bzip2 to 1.0.8 (which sadly didn't reduce the amount of compile warnings, but let's hope it still improves something)

/* spew out a thoroughly gigantic file designed so that bzip2
can compress it reasonably rapidly. This is to help test
support for large files (> 2GB) in a reasonable amount of time.
I suggest you use the undocumented --exponential option to
bzip2 when compressing the resulting file; this saves a bit of
time. Note: *don't* bother with --exponential when compressing
Real Files; it'll just waste a lot of CPU time :-)
(but is otherwise harmless).
