[R] getNativeSymbolInfo for stats on R>=3.0.0

[Francois Rousset]

Dear R users,

Problems with a .Call("logit_link",...) led me to the following test on 
virgin sessions of R2.15.2, R2.15.3, R3.0.0, R3.0.1 (Precompiled windows 
binaries in all cases)
==== begin code ==========
getNativeSymbolInfo("logit_link")
==== end code ==========
This works as expected on R2.15.2 and R2.15.3, but not on R3.0.0 and 
R3.0.1 where I get the message
Erreur dans FUN("logit_link"[[1L]], ...) : no such symbol logit_link

Adding the argument PACKAGE="stats" has no effect. Same error message 
for other functions from the stats DLL, but not for functions from the 
base package [e.g. getNativeSymbolInfo("dqrqy")].

I see that the examples in ?getNativeSymbolInfo have disappeared after 
R2.15.3, but I see no other changes in that documentation that could 
explain the change in the results.

Other information (similar for all versions of R):

Any insight ?
