Write failed to : error on cache writing

[GoogleCodeExporter]

Minify version: 2.1.4
PHP version: 5.2.6

What steps will reproduce the problem?
1. load enough javascript/css to reach cache filename length limit

Expected output:
No errors

Actual output:
"Write failed to {cache_dir}"

Did any unit tests FAIL? (Please do not post the full list)
Havent run tests

Please provide any additional information below. 

Cache failed to write when loading too many javascripts. I changed the line 
Minimify.php : 530 : $name = substr($name, 0, 250 - 34 - strlen($prefix));
to
Minimify.php : 530 : $name = substr($name, 0, 200 - 34 - strlen($prefix));

and the problem was gone. Did the cache tried to write a filename bigger then 
the OS limit?

Thanks, guess I can't trust WP's info on length limitations

Not the best solution.
I have a long path to my /www dir (on windows).
And that length limitation wasn't enough, maybe related to total path length.
changed to: "100 - 34 - strlen($prefix)"
