We have to use the ${BASH_LINENO[*]} syntax which is a syntax error in other shells, so test what shell we are running and use eval. The extra output is only printed if configure is run with bash. On systems where /bin/sh is not bash, it is necessary to say bash ./configure to get the extra debug info in the log. Suggested-by: Eric Blake Signed-off-by: Ian Jackson CC: Kent R.
