Are you sure? Doesn't alpha have libnldbl.a? I think we would have to build
that differently if it's expected to work with compat symbols.

math/libnldbl_nonshared.a references __nldbl__IO_vfscanf.

There are

#if SHLIB_COMPAT (libc, GLIBC_2_0, GLIBC_2_29)
int
attribute_compat_text_section
__nldbl__IO_vfscanf (FILE *s, const char *fmt, va_list ap, int *errp)
{
  int ret = __vfscanf_internal (s, fmt, ap, SCANF_LDBL_IS_DBL);
  if (__glibc_unlikely (errp != 0))
    *errp = (ret == -1); 
  return ret; 
}
#endif

and

But __nldbl__IO_vfscanf isn't marked as a compat symbol and there are
references
to __nldbl__IO_vfscanf in libnldbl_nonshared.a.

As discussed on libc-alpha, libnldbl_nonshared.a should use
__nldbl___isoc99_vfscanf (vfscanf wasn't part of C89).

I think __nldbl__IO_vfscanf should always be defined:
