GNU sed version 4.1.2 - Windows in-place replace problem.

Hi guys

Please keep up the great work with all this Open Source
stuff. We appreciate it.

But bugs keep on coming up!
I'm running windoze 98/xp and there's a problem with
the in-place replace function, with no backup file
specified.

With a backup suffix supplied, it's OK.
I intend to run sed on about 10,000 files. Having a
backup is not practical!

The following are the test cases with two files f1 and f2.

With all files in the same directory, I run sed and I
get the following messages.

sed.exe -i "s/456/555/g" *.txt
SED.EXE: cannot rename ./sedDOSSUX: File exists

The files are not protected in any way. Their contents are:

f1.txt:
123 456 789

f2.txt:
987 456 123

I have contacted Paolo Bonzini who suggests I post this
here.
Regards,
