Description:GCC stops compiling with the following:

warning: cast increases required alignment of target type

Errors for the following files.

A lot of codecs

The codec errors seem to stem from the following line:
int16_t *dst = (int16_t *) pvt->outbuf + pvt->samples;


****** STEPS TO REPRODUCE ******

  [CC] chan_iax2.c -> chan_iax2.o
chan_iax2.c: In function `send_trunk':
chan_iax2.c:6873: warning: cast increases required alignment of target type
gmake[1]: *** [chan_iax2.o] Error 1
gmake: *** [channels] Error 2

  [CC] chan_sip.c -> chan_sip.o
chan_sip.c: In function `sip_addrcmp':
chan_sip.c:3219: warning: cast increases required alignment of target type
gmake[1]: *** [chan_sip.o] Error 1
gmake: *** [channels] Error 2

chan_sip issue is caused by the assignment as noted in code.
char* to a sip_peer*

Codec errors are caused because outbuff is defined as a char* pointer, casting to int16_t breaks alignment.

Did a little more looking around..
To bypass the errors i cast to (void *) to see how many more remain.

Here is my list (excluding codecs):
chan_sip.c: function sip_addrcmp
char* to a sip_peer*

chan_iax.c: function send_trunk
struct iax2_trunk_peer* to struct iax_frame*

iax-parser.c: function  iax_parse_ies
unsigned char* to sockaddr_in*

More coming

I think the better way to go is to use unions to show the conversion.

Corydon, I have updated dundi-parser.c to follow what you did with iax-parser.c
Was unsure about the data+3 part..
