Hi Janis, I am planning to be up and running again this weekend. I have to
start the new GSoC soon! So, could you attach or send me the patch so I can
test it myself?

I have updated the patchset and script to a recent revision. That is, all tests
in gcc.dg that run in i686 with --enable-decimal-float are fixed by either a
patch or an automatic transformation done by the script. I'll send them to you
later.

Hmm, it didn't occur to me to run a regression hunt on the problematic tests to
check whether they are real bugs... let me know how that is working out.
Perhaps I can give you some help.
