Hello all.
This is fascinating in that it seems to be quite emphatic in the message
:

rm -f stage_current

So .. wow.
Could this be because I have different stage languages and
stage1-checking selected?
--enable-languages=ada,c,c++,fortran,go,objc,obj-c++
--enable-stage1-languages=c,c++
--enable-stage1-checking=misc
or perhaps some other mystery ?
