Now I can clearly see the problem.

Take this simple test program:

    $ cat ../test1.c
    #include <float.h> 
    #include <stdio.h> 

    int r1; 
    double ten = 10.0; 

    int main(int c, char **v) 
    { 
        r1 = 0.1 == (1.0 / ten); 
        printf("FLT_EVAL_METHOD %d\n", FLT_EVAL_METHOD);
        printf("1=%d\n",  r1); 
    } 

Compile it, and run it on a "working" host:

    # cc test1.c -o test1
    # ./test1
    FLT_EVAL_METHOD 0
    1=1

Now compile and run on 32-bit Debian 11:

    # cc test1.c -o test1
    # ./test1
    FLT_EVAL_METHOD 2
    1=0

Gonna be hard to create a smaller test case than that.

So back to:

Why is 32-bit Debian not running ins standards conformance mode?

And is there a way to force it to run in standards conformance mode?
