<pre>
    For this C++ code:

extern void g( int);

void f( int a, int b, int c)
{
        if (a <= b <= c)
        {
                g( a);
        }
}

given to a couple of recent builds of clang, does this:

Alphasrc $ /home/dcb40b/llvm/results.20250221/bin/clang++ -c -g -O2 -Wall mar2b.cc
mar2b.cc:6:13: warning: comparisons like 'X<=Y<=Z' don't have their mathematical meaning [-Wparentheses]
    6 |         if (a <= b <= c)
 |                    ^
1 warning generated.
Alphasrc $ /home/dcb40b/llvm/results.20250223/bin/clang++ -c -g -O2 -Wall mar2b.cc

I think it is an error to error on this code and a warning is fine.
