So I ran this test-case again today under native-windows (windows 8
professional, 64 bit, bare-metal, test-case cross-compiled on Fedora with
mingw) and it does fail with:

    2nd ftruncate before unmap: Permission denied

Thus, there was some human error in the execution of my previous experiment and
I take my original comment back regarding the windows behavior.

Since my main use case for Wine is to conveniently run cross-compiled unit-test
suites (e.g. when it's simpler to integrate in a CI environment or quicker
during development) I appreciate that Wine now behaves more like native
Windows.
