Which, IIRC, is what pre 1.63 did also.

Well.. Ultimately the whole of python.jam and the use by BPL build needs to
be scrapped and started over. It was never designed to work with multiple
versions. And having it work in the past for just the two versions was a
miracle it worked. Unfortunately redoing that will take time and will
likely mean that BPL building will need to be different. The most likely
result being that it builds *all*, and *only*, the versions configured. Not
sure what that means for the auto configuration though.
