I don't understand this.  Both of those lines are inside
"#ifdef _NETBSD_SOURCE" blocks, so they shouldn't be visible unless 
_NETBSD_SOURCE is defined, but if it were defined, <sys/types.h> would 
have defined the requisite types.  This suggests to me that something, 
maybe a badly broken system header or maybe your application, is 
defining _NETBSD_SOURCE in between <sys/types.h> and <unistd.h>.

Again, those are precisely the conditions around the declaration of 
pthread_kill(), so something's mangling your preprocessor macros 
between <sys/types.h> and <signal.h>.

You might find it useful to use the -H option of GCC to find out 
precisely which header files are being used and then search them for 
mistaken definitions.
