Compatibility with FreeBSD 2.2.9. Added (RTLD_NOW | RTLD_GLOBAL) to dlopen() test. There is no RTLD_GLOBAL on FreeBSD 2.2.9. Added uint32_t test, with fallback to u_int32_t, similar to uint64_t one. Added fallback to u_int32_t in in_addr_t test. With these changes it is now possible to compile nginx on FreeBSD 2.2.9 with only few minor warnings (assuming -Wno-error).
