[Bug c++/18020] New: issue with enum in a template

[gmorin1 at bloomberg dot net]

Here we go:

gmorin@linux:~> cat foo.cpp
template <typename FOO>
struct bar {
    enum {
        MASK = ((1 << 17)-1)
        , IT_MASK = (~MASK)
        , ITERATION_INC = (MASK+1)
    };
};

int baz = bar<int>::IT_MASK;
gmorin@linux:~> g++ -o /dev/null -c foo.cpp
foo.cpp: In instantiation of `bar<int>':
foo.cpp:10:   instantiated from here
foo.cpp:3: error: enumerator value for `IT_MASK' not integer constant
gmorin@linux:~> gcc -v

This is a Suse 9.0 with gcc from CURRENT OpenPKG. It works if you remove the
template declaration.
