Cpputest has been recently added to msys2 but unfortunately when I build my project under msys2 I got the following issue, which is fixed with this patch:

Uhm, this fix actually broke some of the cygwin builds... did you noticed that?

@basvodde I noticed, I was planning to change the macro to be more restrictive so that cygwin won't be impacted but only msys2, then I've been busy doing other stuff, I will get back on this. Unfortunately the cpputest in msys2 is unusable until I sort this out so I'm currently building it manually as you can see in https://github.com/giuspen/cherrytree/blob/master/.travis.yml avoiding to build that source file at all with the --disable-memory-leak-detection trick

    cd cpputest-3.8
    $mingw64 ./autogen.sh
    $mingw64 ./configure --disable-memory-leak-detection

Sorry @basvodde it's because at the moment I don't have time to debug this issue anymore so I thought to just keep building cpputest on msys2 manually with --disable-memory-leak-detection for now. I noticed that even on msys2 the unit tests of cpputest fail with the changes that make it work for me so maybe it's me doing something wrong. If you have a moment to have a look it's easy to reproduce on msys2, my building instructions are https://github.com/giuspen/cherrytree/blob/master/README.md#building-cherrytree-on-windows if you remove --disable-memory-leak-detection cherrytree unit tests will fail to link with the error at the top of this pull request

Ok, thanks. I'll re-open it then so that we remember to do something about it (especially trying to get this in the automated build)
