The following short script should write a file called testfile
and a file called test_two to the current directory. It seems
that both files should be identical, but in fact one of the LF
characters is missing from test_two. The script works as
expected if read is used instead of <FH>.

It is probably relevant that this report was generated on
Windows 2000 beta 3 RC 0, but the error also manifests on
a separate machine running Windows NT4 Server with Service
Pack 5 installed.

-------- cut here ---->8====
open (OUT, ">testfile");
binmode OUT;
print OUT "\x65\x0a\x0a\x0a\x66";
close OUT;

open (IN, "<testfile");
open (OUT, ">test_two");
binmode IN;
binmode OUT;

# *** The following line does not work
print OUT <IN>;

# *** Replace it with the following two lines and it works.
#read (IN, $buf, -s IN );
#print OUT $buf;

close IN;
close OUT;
