Performance tests
I did some testing of vorbis codec (Winamp plugin) on a Pentium 166 MMX, and
found that the performance is pretty good. I got 3 % cpu utisization if I
turned dithering off, and 5 % otherwise. This was with a 138 kbit song. It's
pretty long to mp3 performance that was 0 to 1 % on that machine for a 128
kbit song.
Also vorbis seems to have a larger working set, because if I play two songs

Compilation failure using mingw-w64 and gcc-5.3.0
Hello,
Upon compiling the flac tree today, after many successful compilations over
the last few weeks, a new error is appearing before compilation bails out.
This is a cross-compilation using gcc-5.3.0 running on GNU/Linux, with the
objects being built for a mingw-w64-x86_64 host.
Among other things, the compiler is looking for windows_unicode_filenames.h
but it isn't there. Also, I'm

Patch to add buffering to decoding too
Can you please wrap the setvbuf in _WIN32 IFDEFs too? Currently
memory usage of FLAC decoding is about 1MB, so this patch is
increasing memory usage tenfold, also for platforms that do not
need this. It is a non-problem on my system anyway.

Patch to add buffering to decoding too
Decoding flac files is also prone to producing fragmented files. NTFS
has the ability to completely avoid fragmentation if it is told the file
size before hand, but that would require using special Windows-only
functions. Increasing the write buffer from the default 512 bytes to 10
MB already reduces the problem tremendously.

Distro Differences?
Hello,
Several of us have been using Wine to play Warhammer Online (http://appdb.winehq.org/objectManager.php?sClass=version&iId=13139&iTestingId=29914). Until recently it worked fine with 1.1.2 on Ubuntu (Hardy). Then the games patcher was updated and it no longer runs instead it hangs without returning when first run. This problem seems specific to Ubuntu as it still works for
