I got this configuration info below from a b2 toolset=msvc,gcc command
I was puzzled to see contradictory information
- __float128 : no
But later
- __float128 : yes
After some confusion, the penny eventually dropped and I concluded that info was first for msvc and then second for gcc, (or was it address-model=32 and 64)?
Could this be easily made clearer?
Even a newline might give clues, but showing the toolset would be even better?
Thanks
