[R] compile R-1.9.1 with Portland fortran

[Jin Shusong]

Dear R-users,

  Has any one compiled R-1.9.1  successfully with Portland
pgcc pgCC and pgf77?  I can not configurate it with
./configure since it told me 
    checking for Fortran name-mangling scheme... configure:
    error: cannot compile a simple Fortran program
  Can any one give me some advice.  Thank you.

  My platform: Linux-2.4.26, pentium4, portland compiler 5.1 

                                 Jin
