  atanl: Simplify for platforms where 'long double' == 'double'.
  
  * lib/atanl.c (atanl) [HAVE_SAME_LONG_DOUBLE_AS_DOUBLE]: New
  alternative implementation.
  * m4/atanl.m4 (gl_FUNC_ATANL): Require gl_LONG_DOUBLE_VS_DOUBLE.
  Determine ATANL_LIBM according to HAVE_SAME_LONG_DOUBLE_AS_DOUBLE.
  * modules/atanl (Depends-on): Add atan. Update conditions.
