Fix bit-field truncation warning message

Browse Source 
Fix copy & paste bug with warning message.

struct X {
      signed int a : 3;
};
struct X g = { 5 };

Before:
s.c(4): Warning: Implicit truncation from 'int' to 'int : 3' in bit-field
initializer changes value from 5 to 5

After:
s.c(4): Warning: Implicit truncation from 'int' to 'int : 3' in bit-field
initializer changes value from 5 to -3

Fixes #1268
