 Hi,
Building current openscenegraph-git, with a fully updated msys2, fails with this error:

I also see a number of warnings apparently related to system and gcc includes.
Any pointer on how to address such issues ?Is it a problem with system headers or with openscenegraph ?

 Fixing system headers is not something i am comfortable with.

Cheers,Philippe.
