>Environment:
System: Linux kiste 2.4.18 #8 Sat Mar 9 15:33:15 CET 2002 i686 unknown
Architecture: i686
SuSE 7.3
glibc 2.2.4 + patches
GNU ld version 020305 20020305
host: i686-pc-linux-gnu

target: i686-pc-linux-gnu
configured with: ../gcc/configure --enable-shared --disable-nls --enable-threads=posix --enable-languages=c,c++,f77,objc
>Description:
The following file tb.C does no longer link, since the static symbol
std::_Bit_count<(bool)1>::_S_bit_count is not definded. The
program compiled and worked sucessfully when I used gcc 3.1
20020302 as compiler. Please fix this problem for the upcoming 3.1 release.

>How-To-Repeat:
#include <bitset>

extern int printf (const char *, ...);
using namespace std;

int main()
{
  enum Color { red, blue, white, black, numColors };
  bitset<numColors> usedColors;
  usedColors.set(red);
  usedColors.set(blue);
  printf("number of used colors: %i\n", usedColors.count());
}
