Hi,

the script debian/test_float_t.sh contains invalid C code which FTBFS with:

make[1]: Entering directory '/home/glaubitz/imagemagick-sh4-new/imagemagick-7.1.2.29+dfsg2'
/tmp/tmp.ynajwKcpye/float.c: In function 'main':
/tmp/tmp.ynajwKcpye/float.c:13:9: error: duplicate case value
   13 |         case(sizeof(long double)):
      |         ^~~~
/tmp/tmp.ynajwKcpye/float.c:10:9: note: previously used here
   10 |         case(sizeof(double)):
      |         ^~~~

The C code in the script looks like this:

int main()
{   
    switch(sizeof(float_t)) {
        case(sizeof(float)):
            printf("float");
            return 0;
        case(sizeof(double)):
            printf("double");
            return 0;
        case(sizeof(long double)):
            printf("long double");
            return 0;
        default:
            printf("????");
            return 1;
    }
}

The code becomes invalid the moment any of these types have the same size
so that the switch statement becomes ambigious.

FWIW, the problem is currently obscured on the buildds due to an internal
compiler error that is fixed with GCC 17 [1].
