I have an HP-UX box (B.11.23) with perl v5.8.8. perl -V:uselargefiles reveals that large file support is enabled (uselargefiles='define';). The trouble is that file tests on files > 2G don't work (ie, "if (-e $filename) {...}"). The test returns "Value too large to be stored in data type" in the $! variable. Any ideas? Thanks.
