[distcc] sockaddr_storage in dparent.c and prefork.c

[Harold L Hunt II]

There was a change from 2.11.2 to CVS in which src/dparent.c and 
src/prefork.c use sockaddr_storage instead of sockaddr.  I do not 
believe that sockaddr_storage is supported by newlib on Cygwin (our C 
library).

My temporary fix was to change sockaddr_storage back to sockaddr. 
Everything compiles again.  Would somebody comment on whether or not 
this change is essential for some other platform?  If the change is not 
essential for some other platform, could we change back to sockaddr so 
that the build isn't broken on Cygwin?

Thanks,

Harold
