[svn] * src/fetch.c: Only leave articles in the requested list if the error
fetching them was fatal. Otherwise article requests will accumulate
indefinitely (e.g retrieving through NNTPcache when it can't find
the body of an article, now or event. Yes, this happened to me; I
had nearly 2000 requests backed up and never being cleared).
* src/group.c: The weekend's change introduced code that causes a bus
error on Sparc ( *(time_t *)p = xxx ). Replace with a safe memcpy,
and also use memcpy when reading the Entry and time items to remove
warnings on Sparc compilation.
