Are pointers to FLAC__int32 and int interchangeable?
There are following functions in bitreader.c:
FLAC__bool FLAC__bitreader_read_unary_unsigned(FLAC__BitReader *br, unsigned *val);
FLAC__bool FLAC__bitreader_read_rice_signed(FLAC__BitReader *br, int *val, unsigned parameter);
FLAC__bool FLAC__bitreader_read_rice_signed_block(FLAC__BitReader *br, int vals[], unsigned nvals, unsigned parameter);
* function FLAC__bitreader_read_rice_signed(...

Are pointers to FLAC__int32 and int interchangeable?
...l without an API
> version bump and I don't think that is currently worth it.
IMHO in this case it makes sense to change:
unsigned *val -> FLAC__uint32 *val
int *val -> FLAC__int32 *val
int vals[] -> FLAC__int32 vals[] or FLAC__int32* vals:
that is:
FLAC__bool FLAC__bitreader_read_unary_unsigned(FLAC__BitReader *br, FLAC__uint32 *val);
FLAC__bool FLAC__bitreader_read_rice_signed(FLAC__BitReader *br, FLAC__int32 *val, unsigned parameter);
FLAC__bool FLAC__bitreader_read_rice_signed_block(FLAC__BitReader *br, FLAC__int32* vals, unsigned nvals, unsigned parameter);
And I hope that...

unsigned int and FLAC__uint32 are used interchangeably
unsigned int and FLAC__uint32 are used interchangeably, leading to
warnings with platforms (e.g. djgpp) where int32_t is long:
