I'd venture to guess that if gnulib had heeded this warning when it was
introduced, then by today, AC_TRY_RUN could have gone away; well, at
least, it would not be necessary any more to remember and explain in
detail the quoting differences of the AC_TRY_* macros over their more
modern counterparts.  I think we all find M4 quoting rules complex
enough already.

First ignoring the warning, then complaining about its existence is
not an excuse.  If you prefer so, we could also make the warning
unconditionally, rather than only with -Wobsolete.  autoupdate exists
to help with updating (and I would send patches if they had a chance of
being applied).

Cheers,
Ralf
