RE: Problem building Dev Tools

I ran into the same problem on a Linux/390 Slackware system.  I wound up
generating this sed file that does the same thing.  I don't have enough
expertise to incorporate this into the build process though.  Apparently
Daniel didn't have enough time to do it either.

I also created a diff to the fixgram script itself.  I didn't trust this as
much as the sed script, because I wasn't able to check to see if it breaks
other platforms.  It seemed to do the trick for me, though.

Slackware 9.0, AMD XP1800, 1 gig memory.

I was (finally) able to catch a bit more of the error...  at least 
something that looks relevent..

In all the coding I have done, seg faults weren't a good thing.  :)
