How do you disable/enable warning suppression for system headers?

Hmm, I'm not sure what to recommend here either. I'd like to see this fixed somewhere, because this increases the warning output for some large C++ projects that I work with (I like to see warnings also). The warnings seemed to be caused by this code in /usr/include/c++/3.3/limits: ========================================================================= 630 static const int digits = __glibcpp_digits (unsigned int); 631 static const int digits10 = __glibcpp_digits10 (unsigned int); ========================================================================= The macros are defined in the same file here: ============================================================================ 134 #define __glibcpp_signed(T) ((T)(-1) < 0) 142 #define __glibcpp_digits(T) \ 143 (sizeof(T) * __CHAR_BIT__ - __glibcpp_signed (T)) ============================================================================ The expanded macros look like: static const int digits = (sizeof(unsigned int) * 8 - ((unsigned int)(-1) < 0)); static const int digits10 = ((sizeof(unsigned int) * 8 - ((unsigned int)(-1) < 0)) * 643 / 2136); I don't really know how to fix this. Maybe introduce a new macro? #define __glibcpp_unsigned_digits(T) \ (sizeof(T) * __CHAR_BIT__ and then use that macro only for unsigned quantities?
