If it didn't work, I'd think that g++ would complain. However, this
isn't really something that needs much discussion since it is easy to
test.
Create the below program and name it 'foo'. Then, make sure that the
current directory is in your path, and type 'foo'.
I get a "it works" when I do this.
cgf
#include <stdio.h>
int
main (int argc, char **argv)
{
if (*argv[0] == 'f')
puts ("it works");
}
