Re: Panic

Hi Arjan,

the underlying GNU binutils issue which causes this was
fixed some 9 months ago. I've been using a new mingw
binutils snapshot for a while which includes it -- it's
available from

    http://www.mingw.org/download.shtml

(look for binutils-2.15.90-20040222.)

You'll still see the warning from GHCi's linker about relocations,
but no need to worry.
