I believe GNU Bison parser generator is capable of generating GLR parsers:

Oh wow, that's pretty cool, wish I had known about it before. Unfortunately flex and bison, when used together in C++, cause a lot of headache (unless you create an "adapter" class that wraps your Flex parser and pass that to Bison). :/
