[R] R CMD SHLIB errors

[sun]

Thanks Prof. Brain,

  Following your suggestion I found the reason of my problem in the document 
''R Installation and Administration' and the links it points to'.

 After I updated to R2.6.2, the RTools's default compiler chaged to gcc4 
while I was using 3.4.x. The error disappeared after I installed gcc4 and 
the default settings from RTools works well now.

Have a nice day!
Sun
