PIO Core 6.1.17 brakes unit testing with googletest

[TeamPlatinum1]

Hi everyone, first I would like to thank you for your work on this project.

After the upgrade to PIO Core 6.1.17 the testing fails in the build stage and throws this error:

.pio/libdeps/native/googletest/googletest/src/gtest-filepath.cc: In static member function ‘static testing::internal::FilePath testing::internal::FilePath::GetCurrentDir()’:
.pio/libdeps/native/googletest/googletest/src/gtest-filepath.cc:60:25: error: ‘_POSIX_PATH_MAX’ was not declared in this scope; did you mean ‘_PC_PATH_MAX’?

The .ini file looks like this:

[env:teensy40]
platform = teensy
board = teensy40
framework = arduino
build_flags = -Ofast
test_ignore = test_native
lib_extra_dirs = lib/custom, lib/public, lib/inbuilt, lib/edited
monitor_speed = 115200

[env:native]
platform = native
test_framework = googletest
build_flags = -D NATIVE
lib_compat_mode = off
lib_extra_dirs = lib/custom, lib/public
lib_deps = google/googletest@1.15.2

After downgrading to 6.1.16 everything works as expected. Let me know if I should provide more info.
