Subject: [PATCH 11/40] Windows: Handle absolute paths in safe_create_leading_directories().
Date: Wed, 27 Feb 2008 19:54:34 +0100	[thread overview]
Message-ID: <1204138503-6126-12-git-send-email-johannes.sixt@telecom.at> (raw)
In-Reply-To: <1204138503-6126-1-git-send-email-johannes.sixt@telecom.at>

In this function we must be careful to handle drive-local paths else there
is a danger that it runs into an infinite loop.
