kill() not found

Hi!

I'm compiling mame-0.171 and seeing

Compiling src/osd/modules/lib/osdlib_unix.cpp...
../../../../../src/osd/modules/lib/osdlib_unix.cpp: In function 'void osd_process_kill()':

The package is using the gcc53 package from pkgsrc, .work.log contains:

signal.h has
#if defined(_POSIX_C_SOURCE) || defined(_XOPEN_SOURCE) || \
    defined(_NETBSD_SOURCE)
int     kill(pid_t, int);

and as you can see above, I've already manually added _NETBSD_SOURCE
to the command line in the hope it would fix this, but it didn't.

Does anyone have an idea why I get that error or how to fix it?
