  error-h: Make less fragile.
  
  * lib/error.in.h: Use #include_next if the system has an <error.h>. Use
  a split double-inclusion guard.
  * m4/error_h.m4 (gl_ERROR_H): Invoke gl_CHECK_NEXT_HEADERS. Set
  HAVE_ERROR_H.
  * modules/error-h (Makefile.am): Substitute GUARD_PREFIX, HAVE_ERROR_H,
  INCLUDE_NEXT, PRAGMA_SYSTEM_HEADER, NEXT_ERROR_H.
