It is bad style: you realy should write 'if (0!=(A=B))' or 'if
(0!=(A=f()))' where that is what you mean, not only to make compilers
happy, but the people succeding you (that's you yourself a year later) too.
 Readability, and thus maintainability, code rules prescribe explicit tests
of assignment results.  Don't use compiler(-switche)s that don't warn about
such constructs.
