  That's true. I have just checked and compiling src/nmath/fround.c 
  without any optimization seems to give the right `round' under Win32
  (at least on a Win3.1 system).
  I will prepare a bug fixed version of rw0623 in few days
  (this bug, the Alt-Gr keyboard bug,....).
  A question: is it sensible that I prepare the binary distribution
  using R-Release (in spite of R-0.62.3)? I would like to have
  a version with at least the (0+0i)^2 and the seq(..,..,by=) bugs
  fixed. And the easiest way it is to use the Release(ed) source.
