CBFalconer dixit:

Due to some people still not getting that $(...) is to
be used over the less portable `...` that can happen ;)

Also an interesting read on the ` character:
http://www.cl.cam.ac.uk/~mgk25/ucs/apostrophe.html

if gcc dummy.c >/dev/null 2>&1 && [ -r "$A_OUT" ] \
    && [ x"$(./"$A_OUT" 2>/dev/null)" = x"^C" ]; then

bye,
//mirabile

PS: I prefer the following ;) but that's not too portable
    since it requires mksh:

if gcc dummy.c >/dev/null 2>&1 && [[ -r $A_OUT ]] \
    && [[ $(./"$A_OUT" 2>/dev/null) = ^C ]]; then
