Yesterday’s upload of RQuantLib 0.3.0 contained one minor oversight: I had failed to update
src/Makefile.winto the new and enlarged set of source files. The proper fix (of using wildcards and implicit rules) was simple, and Uwe Ligges kindly rebuilt RQuantLib on the Windows builder for CRAN using an updated Makefile so that binaries for Windows will be available. This fix will also be in the next upload. Should you need it in the meantime, here is a link to the new version directly from SVN.
