  flac/encode.c: Fix an integer overflow
  
  When encoding a 24 bit multichannel W64 file on a 32 bit system, a
  calculation could overflow resulting in a "got partial sample"
  error and early termination of the encoding process.
  
  The fix was to replace the cast to `size_t` (which is only 32 bits
  on a 32 bit system) with a cast to `uin64_t`.
  
  Thanks to Janne Hyvärinen for helping to track down the problem.

  Fix compile with cygwin
  
  The underscores are wrong. The comment is also correct.
  
  Also remove the configure.ac option. Otherwise it tries to compile the
  windows unicode stuff which POSIX(cygwin) does not understand.

• libFLAC/lpc_intrin_sse41.c : Change usage of _mm_alignr_epi8

  31 janvier 2017, par Erik de Castro Lopo

  libFLAC/lpc_intrin_sse41.c: Change usage of _mm_alignr_epi8
  
  Replace
       a = _mm_alignr_epi8(b, a, n);
  with
       a = _mm_alignr_epi8(a, b, n);
  
  The resulting code is very slightly faster and the binaries slightly
  smaller.
