[CLN-list] mingw-w64

[Kaveh Vahedipour]

Hello folks,

I have tried it. I am just not certain, if it has worked or not and if I was close and just didn't know. It took me an hour or so creating a few constructors so that type ambiguities are handled. Then left it as the tests crashed and I couldn't really spot the error. Segmentation error type of errors. Then I had to go on with my work and didn't test more. If anyone's interested in the branch and the patch, I'd be too happy to make them available. It's a while back though.

Cheers,
Kaveh.
