Have a look at the countless examples and hundreds of unit tests in the Rcpp
package.  Almost all of them work by using the inline package to compile,
link and load shared libraries on the fly.

And yes, it all works fine on Windows XP.  [ We do here that people on
Windows 7 have to fight with security and admin settings though. ]

You "merely" need to install Rtools right and get your PATH settings sorted
out.  This is documented in numerous places.

| "C:/Trading/R/R-2.14.1/share/make/winshlib.mk" SHLIB= OBJECTS=

| LOCAL_SOFT = d:/RCompile/CRANpkg/extralibs/local

| Does anyone have any idea how to fix that ?
| Been trying to fix it for a long time now !
| Thanks in advance !
