I have downloaded R 1.80 recently. I found there was some problems, but I do not
know the reason:

1. I can not do large interation in such new version. For example, 
for( i in 1:36535)
{
if(DAT$age[i]==4) DAT$year3[i]<-DAT$year[i]
}

it seemed to be stuck there, but it computes very quickly in the old version
(such as R 1.40)

2. About RCMD SHLIB command, in such new version, if I use RCMD SHLIB to complie
C program, it will complie all of C program in that directory, although I only
specify one C program.

For example,
RCMD SHLIB weibul.c

but I have dtheta.c in that directory, it will also compile dethea.c.

This does not happen in the old R version.  

Hope you can tell me some reason. Thanks!
