Everyone cares about that! That has nothing to do with performance. It's
simply a broken compiler which needs fixing.

Thanks for the warning. I will keep an eye out for eventual "NTFS is broken
with gcc-2.95 reports"... Although I would make that gcc-2.96 and not 3.0
as minimum requirement. At least I haven't found anything wrong with the
current gcc-2.96...

(Please let's not start another flamewar about whether gcc-2.96 exists or not.)

Best regards,

Anton
