[R] Package Inline under windows

[_]

Hi all,
I installed the package inline (windows-version) but can not compile any 
code, I alway get an error message
"ERROR(s) during compilation : source code errors or compiler 
configuration errors!"

Unfornutanely there is no description where the package finds a 
c-compiler nor where so set the configuration.

Using the linux version, everything works.

Thank's for help !
