infinite recursion in parser, 1.1.1 prerelease

[Ewgenij Gawrilow]

This small program brings the parser in an endless recursion loop:

template <class T>
struct A {
   typedef int TYPE;
};

template <class T>
struct B : public A<T> {
   struct C {
      TYPE i;
   };
};

The parser crashes at the second occurence of `TYPE', in the nested structure
C. This phenomenon has been already observed with the egcs release 1.1, but I
haven't managed to reduce the test suite to a reasonable size that time. Now
it's small enough, isn't it?

The prerelease was tested under Solaris 2.6 on the SPARC platform:

SunOS goldfinger 5.6 Generic_105181-04 sun4u sparc SUNW,Ultra-1

and configured with following options:

--host=sparc-sun-solaris2.6 --prefix=/usr/local/egcs --enable-shared
--enable-version-specific-runtime-libs

I hope, this bug is severe enough to be fixed already in the upcoming 1.1.1
release.
