From f01805fef617d3bf860a58c708abcbb34767d77c Mon Sep 17 00:00:00 2001 From: Stefano Lattarini Date: Wed, 25 Jul 2012 19:51:27 +0200 Subject: [PATCH] configure: testsuite shell set exit traps in shell functions * configure.ac: Check that the shell selected to run the test scripts can set an exit trap in a shell function, without having that trap executed at the termination of the function rather than of the scripts. According to the Autoconf manual, at least AUX 5.3 /bin/sh suffers of such a bug.
