Subject: Fix for Bug #26757: session.save_path defaults to bogus value on win32
X-Git-Tag: php-5.0.0RC2RC1~159
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=32be6f268b59eed7ec5f1bcfd0a88e112a50dd85;p=php

Fix for Bug #26757: session.save_path defaults to bogus value on win32
Merge from branch with one main difference: the default save_path is
set to the empty string on all platforms, whereas the code in the
branch only does so for win32.
