However, the proper functioning of system("") is deeply dependent upon
how /bin/sh implements things.
The testsuite very much should show that the /bin/sh it ends up using
doesn't provide the necessary functionality, or provides it
incorrectly.
Or are you saying that it is better to find this out after libc has
installed and applications fail mysteriously instead?
