Dear Cai,

R-0.49  was released as beta. 
and
it's good to know about compilation problems, even for alpha releases.

My point really was that you should send reports like these to R-devel
rather than R-help.

    XC> Your kind assistance would be greatly appreciated!

I can only help a little:

1) The 'statement is unreachable' is really just a warning.
   [ I also get a few of those when compiling 
     under Solaris 2.5.1 with Sun's cc.]
 
   They shouldn't have caused your compilation problem.

   [now, see below]

Just above lies the compilation error culprit.
Unfortunately, I have no idea what  "Scope Setup phase"  means...

Can you find out what  'fec' is doing, or where  'bu21' comes from?


Probably someone else from the R-devel  list can help you better than I
do...
