The question is if you wouldn't be better served with double-doubles today. You get ~100 bits of mantissa AND you can still vectorize your computations.
Sure. There should be a gcc flag to make "long double" become quadruple precision.
The thing is, my first programming language was x86 assembler and the fpu was the funniest part. Spent weeks as a teenager writing almost pure 8087 code. I have a lot of emotional investment in that tiny rolling stack of extended precision floats.
