[PATCH] Tweak assert -DNDEBUG for the new -Wunused-but-set-{variable,parameter} warnings

[Roland McGrath]

Unfortunately I think this is wrongly incompatible, as Andreas said.
e.g., consider:

#ifndef NDEBUG
static int checker () { ... }
#endif

...
	assert (checker () == 0);
...

Or even worse, it could be hairy macros so that under NDEBUG
the expression is actually unparseable.


Thanks,
Roland
