[PATCH] remove obsolete cpu_info from struct FLAC__BitReader
In FLAC 1.2.0, a new field 'FLAC__CPUInfo cpu_info' was added to the struct FLAC__BitReader. It became useless in 1.3.0 because of various bitreader optimizations. The first patch removes it and also removes FLAC__CPUInfo argument of FLAC__bitreader_init() function. The second patch removes a comment about struct FLAC__BitReader. It seems that it should really belong to <http://git...

...no better solutions to fix the problem, I'd suggest to > #define inline to nothing for MSVC. Looking at the spec again, and using the information in Example 7, I found that if we put the following AFTER the inline definition, it becomes available to other translation units. extern unsigned FLAC__bitreader_get_input_bits_unconsumed(const FLAC__BitReader *br); This appears to be different behavior than other uses of the keyword 'extern' (just like the multiple uses of the keyword 'static'). 6.7.4.7 of the C99 spec suggests that a statement such as the above turns an inline definiti...
