I don't think so, just sounds like it isn't a common extension, do the
comments need to be in column one?
Moving the comments to column one seems to be fixing the problem.
I tested the attached patch on ppc-aix 5.1 (/usr/bin/sed),
alpha-tru64 5.1 (/usr/bin/sed), and solaris 2.5+2.8 (usr/xpg4/bin/sed).
It worked in all cases.
Having this built on-demand is one of the departures from gdbarch.sh
(and why I committed this now, so early in a release cycle). I'd like
to see how unfixable the problem is before abandoning the idea.
OK. I tend to prefer to have all files under revision control, generated
files included. That's because when somebody tells us about a problem,
we are certain about the sources he used. If some of the files are
generated on demand, then we have to consider the possibility of him
having experienced a problem during the generation.
