pi returns 0.7 (PR#1320)

What is `MS2000'?  bug.report() cannot possibly generate that under
Windows, so I presume this is some sort of Windows clone.

You know, people do spend a lot of time carefully checking ports of R
against known results.  Did you really believe that the official R port
for Windows produced pi = 0.7 on an uncorrupted operating system?

Three possibilities occur to me:

1) You have defined an object called pi somewhere in your search path.

2) The base R code has been corrupted (it contains pi <- 4*atan(1), BTW)

3) Your OS has corrupted components and so is computing atan incorrectly.

Try 4*atan(1).  If that is incorrect, re-install your OS. If it is
correct, try re-installing R (which in any case you want to do as 1.4.1 is
current).

Here is an example,

An example of what?

pi;

[1] 0.7

On my home machine running (I think) the same build of R but on WIN98
returns that 3.141... The basic trigometric functions return their > correct values. So it seems to be a problem in the definition of
this constant.
