Hi,

we have an issue since we have added threadapi= .

On 64 bits windows machines we are seen

"FYI, the 64-bit Windows builds are failing due the unit tests exceeding 
the 260 character filepath limit on Windows. Every filepath includes 
|\msvc-14.1\debug\address-model-64\threadapi-win32\threading-multi|. Do 
you know if there is an easy way to shorten this? On the 32-bit builds 
the filepaths don't have |\address-model-64| which is just enough to 
keep them under the 260 character limit so they don't fail."

Is there a workaround to this issue without changing the specific part 
of the test files folder structure?

Best,

Vicente
