Looks like the "dprintf" function in nsping.c is colliding with that of /usr/include/stdio.h, which wasn't there in 10.6

On 10.7:

$ grep -P 'int\tdprintf' /usr/include/stdio.h 
int	dprintf(int, const char * __restrict, ...) __DARWIN_LDBL_COMPAT(dprintf) __printflike(2, 3) __OSX_AVAILABLE_STARTING(__MAC_10_7, __IPHONE_4_3);

Perhaps the steps mentioned ​here will help. They're for Linux but the first error they mention is the same as the one here.

And the second error they mention there, about needing to add -lresolv, is one we've already fixed in r83178.

r84067 should resolve it; let me know if it does not.
