Invalid use of unqualified lookup

[Krzysztof Ciebiera]

I was trying to compile my code with clang and gcc.4.7.2 and it didn't work. I have found solution to my problems at ​http://clang.llvm.org/compatibility.html#dep_lookup_bases

I didn't read C++ specification, but since it doesn't work in both gcc and clang maybe they have the point.

So there are at least two places in lemon code where this-> keyword is missing. In /include/lemon/bits/edge_set_extender.h (probably more). Patch that fixed my problem is following:

526c526
<       return e.direction ? this->u(e) : this->v(e);
---
>       return e.direction ? u(e) : v(e);
532c532
<       return e.direction ? this->v(e) : this->u(e);
---
>       return e.direction ? v(e) : u(e);
