Refactor the same expression check
...
Work out if a function is inconclusive when creating the entry in the
Expressions class instead of when checking the counts at the end. Store
the result in a new bool flag in the ExpressionTokens helper struct.
The pointer to symbol database and ref to list of const functions are
temporarily stored in the Expressions helper class to avoid passing
them in too on every endExpr(tok) call.
Use a const reference to ExpressionTokens in the check loop to avoid
repeating the it->second several times, which clarifies what that code
does.

Whitespace was removed from the append data for every configuration
and every file: n(configuration) * n(files).
Removing whitespace immediately after the append data was read can
significantly reduce the execution time and memory usage.
It also allows further improvement because copies to the temporary
object appendCode are no longer needed.

Fix for same expression separated by commas

Expand the logic for the check for the same expression on both sides of

"alt" variable helping to fudge operator precedence to avoid false
positives.

Fix namespaced types for auto_ptr new[] errors
...
This fixes false negatives for code such as:
std::auto_ptr<foo::bar> p(new foo::bar[10]);
The idea is to find a "new", search for the end token ";", then see if
the declaration ends in a closing square bracket. Also fixes other cases
that checked for "new %type% [" so that they work with namespaces.
