Hey Colin. First thank you for the response. I guess you didn't notice
that I didn't include the "struct" part in my "C" code declaration at first
(it was closer to the bottom of my message). I only added the "struct" part
after receiving this same error (this has solved a similar problem before).
As a result, I still do not understand this error.
Regards
Chris Saunders

This is a C compilation error. FILE_ALLOCATION_INFO is already typedef'ed
from a struct. Drop "struct" from within "sizeof".
