If you grab tamp, look at the rts dir that has a zfp ready runtime using
the 4.6.x source, do a diff on the latest version in case of changes but I
doubt there will be any. It also buds using gpr files.

I probably disabled reversion as you have limited stack. There's a ton of
things you can restrict or turn off.
