[R] Shared library loading in Win R 1071 and previous Win Rversions

[Paul Y. Peng]

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.

Paul.
