Summary: too many arguments in foreign function call

Empirical evidence is that the limit in S-Plus is 128. (The call 
manyArgs(N) constructs a .C with N arguments to a C routine (with 200 
arguments)). 

OK.  I've modifed my patch to bring R's limits to 128, the same as in S-Plus, 
as well as noting that this is the limit in Foreign.Rd.   I suppose that this 
limit is as good as any, and at least means that code written and tested with 
S-Plus won't have to be changed to work with R and vice versa (at least for 
this reason). 

The patch has been uploaded to 
ftp://cran.r-project.org/incoming/dotcall_128.gz

(I hope this will make it into R-1.3.1)
