why do we still have stdnormal_{cdf,inv,pdf,rnd}?

[Robert T. Short]

A comment on this old message.

The stdnormal_xxx functions are for zero mean, unit variance (normal) 
random variables.   The normxxx functions are for the general case but 
call the stdnormal_xxx functions.

Deprecating the stdnormal_xxx functions would break the normxxx functions.
