libstdc++ includes stl_algobase.h from vector.

including <algorithm> makes no difference. (I just left it out to make
the testcase smaller.)

OTOH if I remove <vector> then it compiles just fine.


#include <vector>
#include <algorithm>

using std::swap;

int main() 
{
	size_t a = 1;
        size_t b = 2;
	swap(a, b);
}
swap.C: In function `int main()':
swap.C:10: error: no matching function for call to `swap(size_t&, size_t&)'
