description:
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).
