Yep, that's exactly what happens.  All history-file-related functions (like
checking whether articles are dupes or not) will not work if you forget to
use -fpcc-struct-return on the gcc command line.  With that, everything should
work fine; a friend of mine got C News running on an Encore Multimax with gcc,
and as I recall we didn't have to specify any flags to gcc except for 
-fpcc-struct-return and -traditional.
