Can you explain a bit more details? Only changes I ever had to make were
the slighly different limits, most other things just work fine and relying
on NaN propagation in 3rd party software seems to be rare.

The vax is indeed exception happy, but often this is triggered by bogus
compiler output (like bit shift/mask operations out of range).
