[cfe-dev] patch: boolean bitfield init

[Daniel Dunbar]

g++ 4.01 on OSX, the size of the struct is 2, and x.x is 1 (also for 
an initializer where the low bit is 0) and remains 1 after ++x.x.

Which version are you using?  And how does it deal with the following code?
struct {bool  x : 9;} x = {255}; int c() {return x.x==1;}
