[PATCH] Avoid defining _NETBSD_SOURCE for strict C++

[coypu%sdf.org@localhost]

_NETBSD_SOURCE defines some extra functions, which may use reserved
names. The following patch avoids this problem.

OK?

---------------

Following test case should not error, because major is not a reserved
word in C++.

#!/bin/sh

cat << EOF > test.cpp
#include <sys/types.h>

int major(int a, int b, int c, int d) { return 3; }
int main() {
	return major(1,2,3,4);
}
EOF
c++ test.cpp -std=c++14


Output is:
