[R-SIG-Mac] Math bug in Mavericks build

[Erich Neuwirth]

Some more strange things:

> 2000000000L+200000000L
[1] -2094967296
> 2000000000L*2L
[1] NA
> 2147483647L+2147483647L
[1] -2

(2147483647 = 2^31-1)

So this looks like an integer overflow is not caught for addition, but it is for multiplication



This is my R version:
