Is the attached file what you had in mind?
I tested the script with both bash203 and bash1147, and it worked fine
for me. It changes LFN clashes for the examples,
termcap/grot/termcap.info*, and fixes config.h.in/config.h-in.
It does NOT fix the y.tab/y_tab issue. And to be frank with you all, I
dont think I will be able to fix that in the near future (a lack of
time...). Martin, maybe you can do that part? You were very close to
the solution already, and I think Eli's suggestion should be incorperated.

hth,
 Robert
