Here's a snippet of code that I've used for runtime checks.  There may be
something better, but this works for me:

#define __OS_MAJOR_10_4  8
#define __OS_MAJOR_10_5  9
#define __OS_MAJOR_10_6 10
#define __OS_MAJOR_10_7 11

static int __os_major_version;

void some_initializer() {
    if (sysctlbyname("kern.osrelease", buf, &buf_n, NULL, 0) == -1) {
        perror("sysctl");
        __os_major_version = __OS_MAJOR_10_6; // Set to something reasonable
    } else {
        for(p=buf; *p && *p != '.'; p++);
        *p = '\0';
        __os_major_version = atoi(buf);
    }
}
