[R] R-1.0.0 and Alpha-linux (RH 6.1)

[Brad McNeney]

I just resubscribed to r-help after being unsubscribed for a while so
apologies in advance if I missed part of this. 

I was having some trouble compiling R using gcc on alpha osf5 (and am
still having some trouble with the native C compiler), but found a
suggestion from Greg Snow to try compiling with the -mieee-with-inexact
flag instead of the default -ieee_with_inexact. I get a similar result to
yours (floating point exception just before the prompt) when I compile
with the default, but it seems to work fine with -mieee-with-inexact
(passes all tests). Don't know if this is relevant to Alpha Linux, but
might be worth a try if you haven't already.
