  use unlocked I/O in getdelim
  
  2008-08-27  Paolo Bonzini  <bonzini@gnu.org>
  
  	* lib/getdelim.c (flockfile, funlockfile): Make all of them
  	dummy if one is not available.  Do not touch them if
  	USE_UNLOCKED_IO, instead letting unlocked-io.h do that.
  	(getc_maybe_unlocked): New.
  	* m4/getdelim.m4 (gl_PREREQ_GETDELIM): Check for getc_unlocked.
