In an internal project we came across a situation when building-up an LP program was very slow compared to using CPLEX's native interface. The problem occurs on some special problems, only. The reasons are still unknown.

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:
