Many thanks to Brian and Uwe for their replies. After some changes and recompilation, my dll library now works with R1.7.1. I think the problem was caused by the change in R1.7.1 on calling log1p C function from users' C programs. The answer to my another question is that the older binary versions than rw1070 for Windows are not available in CRAN.
