Hi Takashi,
do you think this could be merged ?
I don't think changing the format in the API header is good at this point, even if it has the same effect in the end. The API has been solid over years. For fixing the build issue, other way round, I'd suggest rather to change to u_int_xx in pcm_misc.c
thanks,
Takashi
thanks, --JS

previously, pcm.h prototyped the functions snd_pcm_format_silence* with u_int_XX types (legacy BSD types from sys/types.h), while the implementation in pcm_misc.c used the C99 stdint.h types uint_XX.
this caused compilation errors on systems where the typedef for u_int_XX and uint_XX is not exactly the same.
we fix it by using the C99 stdint.h types everywhere.
