Did you add the -W flags to your CFLAGS?  Those aren't in there by default..

Anyway, there's lots of warnings, but they seem to be due to the DEBU(G 
macro invention that Kram uses..

Try just compiling but not assembling the output, and then look at the 
assembly..

Just replace -c with -S in the compile line, and call the output .s --

cc -Igsm/inc -Iportaudio/pa_common -Iportaudio/pablio -Iportmixer/px_common -g -Wall -Wpointer-arith -Ilibiax2/src -DIAXC_IAX2 -DLIBIAX  -DSPEEX_PREPROCESS=1 -DSPEEX_EC=1 -DLINUX   -S -o libiax2/src/iax.s libiax2/src/iax.c


Then look for iax_net_read in there..
