I use mingw / msys from location as on wiki suggested.

what is going wrong?

[klutzy]

What's your mingw version? Seems like mingw headers lack some important definitions.

[cnd]

@klutzy 2013072300, and I can't see other with that new "MinGW Installation Manager"

[lilyball]

@Heather Did you solve the problem? If so, what was the solution?

[cnd]

Dowgrade like descripted here #8786

[klutzy]

it was due to #9246.
