CVS head (gcc-3.4), new parser, and should variable names interfere with namespace names?

[Andrew Pollard]

Hi All,

 With the recent parser changes, the following snippet of code now
doesn't compile...

namespace.cxx:
-----------------------
namespace foo {
    int baz(int);
}

int
bar(int foo)
{
    return (foo::baz(foo));
}
------------------------

% g++34 namespace.cxx
namespace.cxx: In function `int bar(int)':
namespace.cxx:8: error: `foo' is not a class-name or namespace-name
namespace.cxx:8: error: `foo' is not a class-name or namespace-name
namespace.cxx:8: error: `foo' is not a class-name or namespace-name
namespace.cxx:8: error: `foo' is not a class-name or namespace-name
namespace.cxx:8: error: `baz' undeclared (first use this function)
namespace.cxx:8: error: (Each undeclared identifier is reported only once for
   each function it appears in.)

Whereas gcc-3.3.x and earlier do compile it.

Is the parser just being more standard conforming, or should it be
able to work out what is meant here? ie should the definition of 'int
foo' be hiding the 'namespace foo'?

Fully qualifing the namespace makes it work again... ie

    return (::foo::baz(foo));

Andrew.
