  roundl: Simplify for platforms where 'long double' == 'double'.
  
  * lib/roundl.c: Include <config.h>.
  (roundl) [HAVE_SAME_LONG_DOUBLE_AS_DOUBLE]: New function.
  * lib/round.c [!USE_LONG_DOUBLE]: Don't include <config.h> a second
  time.
  * m4/roundl.m4 (gl_FUNC_ROUNDL): Require gl_LONG_DOUBLE_VS_DOUBLE.
  Determine ROUNDL_LIBM according to HAVE_SAME_LONG_DOUBLE_AS_DOUBLE.
  * modules/roundl (Depends-on): Add round. Update conditions.
