The patch is appended. It adds 
static bool QFileInfo::isAbsolute(const QString &path);
static bool QFileInfo::isRelative(const QString &path);

and fixes
static bool QDir::isAbsolutePath(const QString &path);
static bool QDir::isRelativePath(const QString &path);

all the above mentioned methods are based on
static bool QFSFileEngine:isAbsolutePath(const QString &path);
static bool QFSFileEngine::isRelative(const QString &path);

which makes the internal string compare functions accesable

PS: I have not thoughed the non static related member methods

Regards
Ralf
