--- Comment #5 from xeioex <xeioexception at gmail dot com> ---
My question is more practical. For example while `-fexcess-precision=3Dstan=
dard`
fixes the problem in GCC. But, I am left with the same problem regarding ot=
her
compilers. At least am looking for a way to detect excessive precision as s=
oon
as possible (during configure time).

Tried to use FLT_EVAL_METHOD

t.c
```
#include <stdio.h>
#include <math.h>
#include <float.h>
#include <fenv.h>

int main(){
  printf("%d\n", (int) FLT_EVAL_METHOD);
}
```

1) gcc -o t t.c && ./t
2

2) gcc -fexcess-precision=3Dstandard -o t t.c && ./t
2


How am I expected to use FLT_EVAL_METHOD correctly?=
