commit 40b56994dda79653c902977423f349efa55cf21e
Author: Adrian Johnson <ajohnson at redneon.com>
Date:   Mon Oct 17 20:33:03 2011 +1030

    utils: Add GooString arg to parseargs and use for paths in pdftocairo
    
    <sys/param.h> and MAXPATHLEN is not available on windows. Avoid the
    need to know the max path length by using GooString for the path.
