Update.
2001-11-28 Ulrich Drepper <drepper@redhat.com>
* libio/genops.c (_IO_flush_all_lockp): New function. The same code
as the old _IO_flush_all but lock only if parameter is nonzero.
(_IO_flush_all): Call _IO_flush_all_lockp with 1 as parameter.
* libio/libioP.h: Add prototype for _IO_flush_all_lockp.
* sysdeps/generic/abort.c (fflush): Define to _IO_flush_all_lockp(0)
if libio is used.
