--- Comment #4 from Richard Biener <rguenth at gcc dot gnu.org> ---
And that hook may be new.  Note that calling sincos explicitely of course
works.

I see

bool
linux_libc_has_function (enum function_class fn_class)
{
  if (OPTION_GLIBC)
    return true;
  if (OPTION_BIONIC)
    if (fn_class == function_c94
        || fn_class == function_c99_misc
        || fn_class == function_sincos)
        return true;

  return false;
}

where likely cygwin does not use GLIBC nor BIONIC (android).  Indeed cygming.h
has

#undef TARGET_LIBC_HAS_FUNCTION
#define TARGET_LIBC_HAS_FUNCTION no_c99_libc_has_function

Confirmed as enhancement.
