Subject: [PATCH] Fix NativeCommandError when running test suite
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Temporarily set $ErrorActionPreference to "Continue" around the test
suite execution.  With the global "Stop" preference, any stderr output
from the native executable (e.g. Boost.Test banner/progress text) was
being wrapped as a PowerShell ErrorRecord and immediately triggering a
terminating NativeCommandError — even when the test suite passes.

The exit code is already checked explicitly via $LASTEXITCODE, so
relaxing the preference for this one invocation is safe.
