CYGWIN_NT-5.0 OLFDEV1 1.3.10(0.51/3/2) 2002-02-25 11:14 i686 unknown
>Description:
	When I try to call a function with a parameter of "min< double >", it
complains with the error:
no matching function for call to `matrix_min_path (Matrix<double> &, plus<double>, {unknown type})'
>How-To-Repeat:
	g++  -g -I /home/nyap/opt/mtl-2.1.2.20/include -Wall   asdf.cc   -o asdf

where asdf.cc contains:
#include <algorithm>

template < typename BinaryFn >
void test(BinaryFn fn)
{
    fn(0, 1);
}

int
main(int argc, char *argv[])
{
    test(min< double >);
}
>Fix:
	The following is a workaround:
#include <algorithm>

template < typename BinaryFn >
void test(BinaryFn fn)
{
    fn(0, 1);
}

int
main(int argc, char *argv[])
{
    const double &(*minFn)(const double &, const double &) = min< double >;

    test(minFn);
}
