This is an array bounds guard. I guess it's defensive programming vs  
warning. Making OggzStreamContent a (signed) int is probably the  
safest, but I don't know the rules for enums.

These are fixed in libogg svn r14463. Guess we should do a release!

The content_types array should be declared 'const char *' here.

This is because qsort's compare function should take two 'const void  
*' arguments, but what's really being passed are 'char **'.

These are all innocent, so I'll leave them to kfish to resolve as he  
likes.
