re PR libfortran/21324 (#undef GFC_CLEAR_MEMORY causes testsuite failures)
2005-05-12 Thomas Koenig <Thomas.Koenig@online.de>
PR libfortran/21324
* runtime/memory.c: Don't define GFC_CLEAR_MEMORY (it's a
performance hog).
* io/open.c (new_unit): Zero freshly allocated memory for
unit structure.
* io/unit.c (init_units): Zero freshly allocated memory for
STDIN, STDOUT and STDERR.
* io/unix.c (open_internal): Zero freshly allocated memory
for unix_stream.
(fd_to_stream): Likewise.
