[Bug-gsl] Confluent Hypergeometric 1F1 request

[Raymond Rogers]

I believe I have found some problems and perhaps a solution in the 1F1 code.
Could somebody (s) evaluate the following in Maple and Mathematica and 
post the results?
1F1( -1, -2, -4)

The online Mathematica answer is: -1.000000000000000000000
Whereas GSL gives 0.0549469166662

If anybody is willing to discuss the calculation details; I would be 
grateful.   I have reached a conclusion that should be double checked.
