This is pretty darn odd... The quick-exit syndrome with an FP error
can only occur from misconfiguration of the IEEE options I think, but
why would that be different between 6.0 and 6.1?

2 ideas:

1. what do you get from running tools/config.guess? If it doesn't
   match alpha*linux in configure.in, you'd certainly get in trouble.

2. are we using the proper form of the ieee option? configure.in sets
   -mieee (do you see that in compiles too?), but it may be that it
   wants -mieep-fp, -mieee-with-inexact or whatnot... "gcc --help -v
   2>&1 | grep ieee" works with gcc 2.95, but not with egcs 1.1.2 on
   intel, but you could try.

Well, three ideas: does the 6.0 binary run on the 6.1 machine?
