[Bug c/31273] New: Erroneous bitfield conversions to boolean values

[eric dot lemings at roguewave dot com]

The following code compiles fine in GCC 4.1.

enum E { e };
struct S {
  E v:5;
};
S s;
int main() { if (!s.v) return 0; }

In 4.2 (20070307), it gives the following error:

test.cpp: In function 'int main()':
test02.cpp:6: error: could not convert 's.S::v' to 'bool'
test02.cpp:6: error: in arguument to unary !

Jim Wilson has suggested this is a bug due to recent patches to the 4.2 branch.
