yes, it has been reported (May 11, R-help) for pweibull() and
was tracked to a bug in the new R internal expm1() function
which only shows when no system-internal expm1() function is
present. Hence the problem has only been seen on Windows.

It has been fixed in "R-patched" for quite a while, and we
recommend you get "R-patched" pre-compiled for Windows
by Prof Ripley

Thank you for reporting it anyway (it was not obvious if you haven't
followed R-help closely).
