What does 'test' in testcases do?

[Christopher Jefferson]

I decided to try to trace the reason for adding:

bool test __attribute__((unused)) = true;

into tests. It seems to be from the following piece of code in
util/testsuite_hooks.h:

#ifdef _GLIBCXX_ASSERT
# include <cassert>
# define VERIFY(fn) assert(fn)
#else
# define VERIFY(fn) test &= bool(fn)
#endif

So, if we have assert we call it, else we do 'test &= bool(fn)'.

However, as far as I can see, no test does anything with 'test', so I
think this is ignoring any failing tests on any platform which does
not have 'assert'?

If I am understanding correctly, this should probably be fixed. I'm
not sure what the intention was.. probably returning 'test' from main?
Is there still platforms without assert where this matters?
