Hossein,

Thanks for your reply. My apologies for providing such a cryptic description
of my problem and also for the misleading subject; I didn't mean to imply
that I thought the compiler was at fault.

I'm using Dev-C++ 4.9.8.0. A search on Google turned up a
number of references to this error but no solutions as far as I could tell.
I tried your suggestions of placing "()" or a blank after the code fragment
seqref<T> but that didn't change anything. My knowledge of C++ is minimal
and I don't know how to follow up on your suggestion regarding the
"name as the parent of its iterators of type RandomAccess".  I checked the
on-line version of the GNU compiler manual but didn't find anything helpful.
Below I have included the output of the compiler log and a somewhat longer
fragment of the code. I hope this will provide a few more clues to you or
some other kind C++ guru.
Thanks,
Gary Richardson
