Integrate[z (1-z^2)^(-1/4),{z,-1,1}]

 Hi MathGroup(ers),

 the above integral (it is just an orthogonality relation for 
 Gegenbauer polynomials) gives me an error in in ReplaceRepeated(!)
 and the result 3/4. For symbolic a symbolic exponent the result is
 1/(1+a). For positive exponents the result is 0.
 How to manipulate the integral tables to give me 0 for negative real arguments
 (>-1/2).
 
 Thanks for an idea
