A quick question on template member syntax, and whether
egcs is behaving correctly:
I have a line of code that looks like this (e is an STL
iterator):
myAttribute attr = (*e).getNode()->getAttribute<myAttribute>();
egcs complains about a parse error before `>'.
myAttribute is defined in a header file included by the source
file. This worked before I used template members to get at
attributes (direct request to the attribute manager object).
Is my code incorrect, or is this a bug in egcs? I couldn't
find anything in [3rd] to indicate that this would be a problem.

The `template' keyword is mandatory just after `->' when you
explicitly specify template arguments for a template member function,
in order to disambiguate. If it is missing, the expression must be
parsed as:
(((*e).getNode()->getAttribute) < (myAttribute)) > ()
that is, `<' is taken as a less-than operator.

Your code is incorrect. You need to say:
(*e).getNode()->template getAttribute<myAttribute>();
