[Rd] R 2.3.0 (alpha) on FreeBSD 6.1 fails make check-all

[Andrew Robinson]

I get:

> Rhyper <- scan()
1: 16 11 11 15 11 13 13 12 13 10 10  7 11 14 13  9 14 13 13 11 
21:
Read 20 items
> Phyper         <- phyper   (Rhyper, m = 40, n = 30, k = 20) 
> qhyper(Phyper, m = 40, n = 30, k = 20)                             
 [1] 16 11 11 15 11 13 13 12 13 10 10  8 11 14 13  9 14 13 13 11


The 12th element (8) differs from the input (7). 


> Phyper <- phyper (7, m = 40, n = 30, k = 20)
> qhyper(Phyper, m = 40, n = 30, k = 20)
[1] 8


If I do this using 2.2.1 then the input and the output are identical.
