[R] Source installation error: "gfortran and gcc disagree on int and double ...

...  configure: error: Maybe change CFLAGS or FFLAGS?"

Dear list, 

This problem has been posted before
(http://finzi.psych.upenn.edu/R/Rhelp02a/archive/7982.html), but
suggestions did not help. My machine:  AMD Duron 800 MHz, MandrivaLinux
10.2, gcc (and gfortran): 4.0.1, R source: 2.3.1. I had to set CPICFLAGS
and FPICFLAGS to "-fPIC". I tried ./configure with default CFLAGS and
FFLAGS flags and with "-O3 -g" with the same error message. 

How can I pass the error?

Thank you in advance, 

Mike.
