    Make autogen.sh exit properly if a command failed
    
    * autogen.sh: Apparently, sub-shells do not inherit the state of the
    -e option, and even ignore explicit uses of 'set -e' within the scope
    of the sub-shell.  In order to work around this stupid behavior, test
    the exit status explicitly for commands executed in a sub-shell.
