[GCC-XML] Not Forgetting Original Typedefs

[Phil Thompson]

Hmm, with more investigation it seems things aren't very consistent.

typedef int foo;

void bar(foo);

class Klass
{
	void meth(foo);
}

The XML from the above defines the bar() argument as int and the meth() 
argument as foo.

This means it's less of a problem than I first thought it was - but it now 
looks more like a bug.
