"suggest parentheses around assignment used as truth value" warning bug

[Josh Wilmes <jwilmes at cisco dot com>]

The file "test.cpp" (attached) uses an assignment as a truth value in three 
places.   However, one of them (where it occurs inside a templated class) does 
not generate a warning.   We just found such a bug in a program here and were 
surprised that the compiler hadn't caught it.

I didn't see any mention of this bug in the 2.95.2 release notes, but if it 
has already been fixed, let me know.

Thanks,

--Josh
