Oh, I noticed the following:

../../../gcc/libgfortran/intrinsics/c99_functions.c: In function 'copysignl':
../../../gcc/libgfortran/intrinsics/c99_functions.c:259:1: warning: infinite
recursion detected [-Winfinite-recursion]
  259 | copysignl (long double x, long double y)
      | ^~~~~~~~~
../../../gcc/libgfortran/intrinsics/c99_functions.c:261:10: note: recursive
call
  261 |   return __builtin_copysignl (x, y);
      |          ^~~~~~~~~~~~~~~~~~~~~~~~~~

copysignl is broken too.
