Just a side note:
Mac OS X 10.4, the currently oldest supported release by VLC 0.9.x,  
requires code compiled by GCC 4.0.1. GCC 4.2 is only supported for  
10.5 and the forthcoming 10.6. As 10.4 is still widely used in the Mac  
community, I wouldn't like to drop support for it any time soon (at  
least not until 10.6 is officially released next summer).

Obviously, your patch still compiles nicely using the 10.4u SDK :-)

Best,

Felix
