So does 2.0 provide the necessary software to support 68040 transcendental
instructions transparently? Or will 040 board vendors (of which C= will surely
be) have to provide some patch programs to replace the math lib entry points
for the trans function and provide FLINE trap handlers for those programs
using the FPU directly?
