Compilation Error with Example

[wfairclough]

I am getting this compilation error with g++. And my main.cpp is the example for this link: http://code.google.com/p/jzon/wiki/WritingFiles

My g++ version output is:

macbook-pro:Jzon v2-0 will$ g++ --version
i686-apple-darwin11-llvm-g++-4.2 (GCC) 4.2.1 (Based on Apple Inc. build 5658) (LLVM build 2336.11.00)

g++ -Wall -I. jsonWriterMain.cpp Jzon.cpp -o jsonWriter

For starters you seem to need this workaround: http://code.google.com/p/jzon/issues/detail?id=8#c6
Can you post the errors that are left after applying the patch?

The last few commits have fixed a lot of compiler issues. I'm going to assume this problem has been fixed too.
