[jira] [Created] (ARROW-4900) mingw-w64 < 5 does not have __cpuidex

Jeroen created ARROW-4900:
-----------------------------

             Summary: mingw-w64 < 5 does not have __cpuidex
                 Key: ARROW-4900
                 URL: https://issues.apache.org/jira/browse/ARROW-4900
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: Jeroen


The current R toolchain uses mingw-w64 version 3. Building arrow fails because arrow uses __cpuidex which was introduced in mingw-w64 version 5: https://github.com/mingw-w64/mingw-w64/commit/8e921f2a87fb70564cbcf40676daee93ea0cae3a

We need a polyfill for this.
