I think the problem is that the code tries to use std::deque<Entry> as a
member of struct Entry, before it is completely defined.  This is not
allowed by the standard, although some libraries (e.g. GNU libstdc++)
apparently permit it for some container types.

You could try to work around it with -fdelayed-template-parsing, but I
am not sure if it will help.  Alternatively, compile the code with
libstdc++, or rewrite it to conform. :-)
