When used in the context of groff-1.22, the script does the following: if echo ./conftest.sh | (csh >/dev/null 2>&1) >/dev/null 2>&1;
On my PC, the script hangs at that line (csh doesn't exit). Admittedly, its my fault: I've modified my .cshrc to do this: if ( $?prompt ) exec /bin/bash -i and removing my hacked .cshrc solves it. However, wouldn't it be cleaner for configure to use the '-f' option to 'csh' and avoid running user .cshrc scripts altogether? regards, Jon
