[vlc-devel] Problems with Mac OS X compile

[Derk-Jan Hartman]

Where and when are you seeing this problem exactly. ?

The primary commit that changed this was http://git.videolan.org/?p=vlc.git;a=commitdiff;h=084f988fe584d9d2075ccfd7d7c35bb1829b726c
I'm not sure why this was done, and this developer has since left the  
project...
I agree with you that the current situation is incorrect, but I'm also  
hesitant to change, without knowing why it is written as it is.
