example that could warn
sometimes gcc will give a warning like:
warning: the address of 'foo' will always evaluate as 'true'
if the address foo is used in a conditional expression.
It would be useful if there was also a warning of the form:
warning: the comparison of 'foo' with itself will always evaluate as 'true'
if the code does "if (strcmp (foo, foo) == 0)" or similar.
