fc360735ce Fix a regression that severely impacted compression levels. 
Regression was introducted in commit 8bbbf56403
(Feb 1 19:58:09 2012) when fixing compiler warnings. In src/libFLAC/lpc.c the
line:

        ref[i] = (r/=err);

was erroniously removed because the left hand side, ref[i] was never used.
Obviously, the correct thing to do was to replace that line with:

        r /= err;

This code has not been officially released. The only people who would have
been affected are people who compiled FLAC from git between February and
now.

The only adverse affect of this error was that compression ratio would have
been severely compromised. No audio is lost, and if anyone has a file that
compressed with a bad version of FLAC can decompress it to WAV and then
re-compress with a fixed version.

9b7cb22f84 Update and improve autotools build 
- INCLUDES is deprecated, and CPPFLAGS is an user-defined
  variable, use the proper AM_CPPFLAGS instead

- Remove FLAC__INLINE definition, providing proper
  replacement for MSVC compilers.

- Detect if we have C99 's lround and provide a replacement
  for windows...

Josh Coalson
0975843bed first pass at making an integer-only flavor of the libraries. move FLAC__real out of ordinals.h to src/libFLAC/include/private/float.h, add FLAC__double and FLAC__float and use these everywhere instead of double and float, and don't typedef FLAC__real/float/double when building in integer-only mode. still need to provide integer substitutes in several places. 2004-10-20 00:21:50 +00:00
