Since the test isn't trying to link the program anymore, you should be able
to drop this variable entirely (as well as the calls to glCreateProgram()
and glAttachShader() below).

You can drop this if-block.  Since you've already checked that argc is 2,
it's impossible for argv[1] to be NULL.

If the command-line argument doesn't match any of the strings in the
"valids" array, then we can't just fail.  We need to verify that a compile
error occurred.  I've sent out a suggested fix.
