Hi,

I have a setup to compile ffmpeg with Microsoft Visual Studio in an 
msys2 environment. Today I tried to compile with the new VS2015 and 
received an eror very late during compile. (Error message in German btw.)

CC      ffmpeg.o

I entered this error into an internet search engine and found out this 
error was reported after an early community preview had been released. 
Now that RTM has appeared I wonder what's the status of this patch: 
https://ffmpeg.org/pipermail/ffmpeg-devel/2015-March/169831.html --- or 
if there's a solution.


Best,
