I'm using Maxima 5.27.0 released May 5, 2012
If you don't have float2bf set to "false", you won't see the warnings... but they're still happening right?

You should be getting true bigfloat precision.? I'm guessing you're
using a pretty old version of Maxima. I'm pretty sure those warnings
were removed a long time ago, and they don't occur with the current
git version.
