Subject: fork/socket, gethostnamebyaddr, wait3

We have ported our client/server software to Win95/NT using
the gnuwin32 gcc compiler version b18. We found the following 
problems/bugs:

1) fork/socket: An Unix child process inherits all open file descriptors,
   including any socket descriptor. In the gnuwin32 environment the socket 
   descriptors in the child process,i.e. after a fork are  NOT available.
   Socket descriptors are NOT inherited.

2) gethostnamebyaddr always return 0; In b17 this function was not implemented
   but in b18 it is. The return 0 is still in the code but should be 
   return ptr. (net.cc) (May be Sergey can fix this in one of his new patches?).

3) Wait3 is not implemented. Is there a way around this? I.e. is it possible
   to use waitpid for wait3?


Except these problems, porting was easy. 

Regards,
