- Updates bzip2 to 1.0.8 (which sadly didn't reduce the amount of compile warnings, but let's hope it still improves something) git-svn-id: svn://svn.code.sf.net/p/irrlicht/code/trunk@6282 dfc29bdd-3216-0410-991c-e03cc46cb475

# Bzcmp/diff wrapped for bzip2,

# Bzcmp and bzdiff are used to invoke the cmp or the diff pro-
|
|
# gram on compressed files. All options specified are passed
|
|
# directly to cmp or diff. If only 1 file is specified, then
|
|
# the files compared are file1 and an uncompressed file1.gz.
|
|
# If two files are specified, then they are uncompressed (if
|
|
# necessary) and fed to cmp or diff. The exit status from cmp
|
|
# or diff is preserved.
