Implicit-declaration (missing #include) warnings

Building dateutils-0.4.6 on OS X 10.13...

yuck.c:1175:6: warning: implicit declaration of function '_NSGetExecutablePath' is invalid in C99 [-Wimplicit-function-declaration]
        if (_NSGetExecutablePath(buf, &z) != 0) {

Hey Daniel, thanks for reporting this. I pushed a fix (00c8383db) to master.

Looks like this can be closed now.

Building 0.4.10 , time-core.c looks clean in this regard. But clitosis.c is still:

clitosis.c:383:7: warning: implicit declaration of function '_NSGetExecutablePath' is invalid in C99 [-Wimplicit-function-declaration]
                if (_NSGetExecutablePath(buf, &bsz) < 0) {
                    ^

Needs the same fix that yuck.c got in a10d39c1a6114cbd152e04f072ce580918fa90a4:

#if defined __APPLE__
# include <mach-o/dyld.h>
#endif  /* __APPLE__ */
