And part of the portability warnings in autoconf.texi.
Hmm. I tested some more, only to add to the confusion. Apparently
pdksh does not (always?) execute the EXIT handler when it exits from
a signal (!=0) handler, so that seems very unreliable.
For now I have only applied the aclocal.in fix which was
uncontroversial, to master and branch-1-10.
