Hi Steffen,

Most of these are conversions between various integer types. I think 
the majority of these are in fact correct code. It would be quite a 
lot of worth to fix these and I am not sure that it would be worth the 
effort. I would recommend to simply disable that warning for now.

The same is true for various signed/unsigned mismatch warnings. BTW, 
some warnings lack line numbers and can't be checked ATM.

After filtering these out, the following remain:

This seems to imply that the compiler does not know that 
ap_log_assert() does not return. Is there some equivalent of 
__attribute__(noreturn) for VC?

I don't know what l_timeval is. But if Windows ldap uses something 
different than timeval, maybe there should be some #ifdef magic to 
deal with that.

This sounds like it could be a problem. Can some Windows dev take a 
look?
