Patch confirmed to work as advertised, committing for rawhide
Re-opening, still FTBFS, but apparently now for other reasons(s).
Current failure appears to be something related to openmp support, so adding (hopefully temporary) workaround: configure ... --disable-openmp Keeping this bug open to track the openmp issue, and hopefully be able to restore the feature.
In my hurry to document and fix stuff looks like I filed 2 bugs, this particular one is fixed, the other openmp issue is tracked in bug #1671080
