Configure case insensitive filename auto-complete

[Bruza]

Is there a way to make my min-buffer filename auto-complete case
sensitive? I personally think it's really annoying having to remember
the case of the first letter of your file (is it "MySQL.txt" or
"mysql.txt"??) when using filename auto-complete search. After all,
the auto-complete is meant to help you so that you don't have to
remember exactly what the filename is...

Can someone help? Thanks in advance,
