    Per https://gcc.gnu.org/bugzilla/show_bug.cgi?id=113679#c11 seems clang is buggy:

> $ clang -O2 -m32 -mno-sse -mfpmath=387 -fexcess-precision=standard
```c
#include <float.h>

int main () {
#if FLT_EVAL_METHOD == 2 && LDBL_MANT_DIG == 64 && DBL_MANT_DIG == 53
  if ((double) 191.18831051580915 == 191.18831051580915)
 __builtin_abort ();
#endif
}
```
should always succeed, because if FLT_EVAL_METHOD is 2, it ought to be evaluated as (long double) (double) 191.18831051580915L == 191.18831051580915L and (double) 191.18831051580915L is 0x1.7e606a3c65c95p+7 while 191.18831051580915L is 0x1.7e606a3c65c9503ap+7L, so they aren't equal.

With gcc 13.2.1 the program terminates, with clang 17.0.5 it aborts with core dump.
