I agree that the priority is to use a portable solution.
But among them, the standards conforming should be preferred--it's kind of
"future portability".  Moreover, people will read the scripts: we shouldn't
teach them portable non-conforming hacks, if there are portable conforming
ones available.  ;-)

And it is also the clener one.
Proposed patch attached.

I'm also attaching a proposed patch for the Autoconf manual.
Could someone please verify whether "trap - SIG" is supported on recent
versions of Solaris and HPUX?

Have a nice day,
